Post-Op Instructions After Glaucoma Laser or Surgery
What to Expect Immediately After Your Glaucoma Procedure
What happens in the first hours and days depends on whether you had a laser treatment or an incisional surgery. Our team will guide you through the specific steps for your procedure type.
After your procedure, our team will bring you to a recovery area where we monitor your comfort level and, in many cases, your eye pressure and vital signs. If you had a laser procedure such as selective laser trabeculoplasty, we may check your eye pressure within 30 minutes to two hours after treatment, depending on our protocol. After incisional surgery such as trabeculectomy or tube shunt implantation, we typically monitor you for a longer period and schedule a follow-up visit for the next day.
You may rest in a reclining chair or on a bed while the initial effects of any numbing drops or sedation wear off. Before you leave, we will review your medications, answer any questions, and schedule your first follow-up visit. Some laser procedures are done in the office with little to no recovery time needed.
- Keep any eye shield or patch in place as directed until your first follow-up.
- Do not rub or press on your treated eye, even if it feels scratchy or irritated.
- Expect blurred vision and light sensitivity for at least the first few hours.
- Bring all your eye drops, both new and pre-existing, to your follow-up appointment.
- Know how to reach our after-hours on-call service in case you have urgent concerns.
Laser procedures such as selective laser trabeculoplasty and laser peripheral iridotomy are typically less invasive, so recovery is often quicker and discomfort is usually mild. Selective laser trabeculoplasty usually causes minimal inflammation and may require only short-term anti-inflammatory drops or sometimes no new drops at all. Laser iridotomy can produce more light sensitivity and inflammation for a few days and typically requires a short course of steroid or anti-inflammatory drops.
Incisional surgical procedures require more intensive healing and longer activity restrictions. Trabeculectomy creates a filtering bleb under the conjunctiva and often involves significant early blur, redness, and swelling that can last several weeks. Tube shunt surgery implants a small drainage device and has a similar recovery timeline, though the risk profile and long-term monitoring needs differ. Minimally invasive glaucoma surgeries, often called MIGS, are frequently combined with cataract surgery and generally have shorter recovery periods, typically one to three weeks, with fewer restrictions than traditional filtering surgery.
- Laser recovery usually involves fewer restrictions and a shorter or no new medication schedule.
- Trabeculectomy and tube shunt patients may experience significant redness, swelling, and blurred vision for several weeks and require strict activity limits.
- MIGS procedures often follow cataract post-op protocols and have intermediate recovery expectations.
- Your personalized recovery plan will depend on the specific type of glaucoma treatment you received.
You will need a responsible adult to drive you home if you received sedation, had your eye dilated, are wearing an eye patch or shield, or have blurry vision. Even after some laser procedures with only numbing drops, we recommend having a driver because your vision may be temporarily unclear or you may feel more anxious than expected.
Plan to have someone stay with you for the first 24 hours if you had incisional surgery, in case you need assistance or experience any unexpected symptoms. Avoid making important decisions or operating machinery for the rest of the day. Rest at home with your head comfortably elevated on a pillow to help reduce swelling and improve comfort.
It is common to have blurry or hazy vision immediately after your procedure. This can be due to dilating drops, ointment we placed in your eye, or mild swelling of the cornea. Some patients see halos around lights or notice their vision is dimmer than usual for the first few days.
After laser procedures, these changes often improve within a few days. After incisional surgery, vision can remain blurred for several weeks, and you may notice fluctuations or shifts in your prescription due to changes in the shape of your eye. If your vision becomes suddenly worse or you lose vision, contact our office immediately, as this may signal a complication that needs urgent attention.
Using Your Post-Operative Eye Drops and Medications
Medication needs vary widely depending on your procedure. Laser treatments may require only a brief course of anti-inflammatory drops or no new drops at all, while incisional surgeries typically require a combination of steroid, antibiotic, and pressure-lowering drops for several weeks.
We will prescribe a combination of eye drops tailored to your procedure to reduce inflammation, prevent infection if needed, and control eye pressure. Each drop has a specific purpose and schedule, so it is important to use them exactly as directed. Your written instructions will list each medication, how many times per day to use it, and for how long.
Unless we specifically tell you to stop or change them, continue using your pre-existing glaucoma drops along with any new post-operative medications. Post-operative plans vary by procedure and by how your eye pressure responds, so always confirm your complete drop schedule with us before leaving your appointment. Set reminders on your phone or use a medication chart to keep track of doses throughout the day. Spacing your drops by at least five minutes ensures each one has time to absorb properly.
Wash your hands thoroughly with soap and water before handling any eye drop bottle. Tilt your head back or lie down, and gently pull your lower eyelid away from your eye to create a small pocket. Squeeze one drop into the pocket without letting the bottle tip touch your eye, eyelid, or lashes.
- Close your eye gently for one to two minutes without squeezing or rubbing.
- Press lightly on the inner corner of your eye near your nose to keep the drop from draining into your tear duct.
- Wipe away any excess liquid with a clean tissue.
- Wait at least five minutes before putting in a different type of drop.
- If a drop is a suspension, shake the bottle gently before use if the label instructs you to do so.
- If you are prescribed an ointment, wait ten minutes after your last drop and apply ointment last.
- Do not wear contact lenses during your recovery period unless your surgeon specifically clears you to do so.
- Replace the cap tightly after each use to keep the bottle sterile.
Steroid or anti-inflammatory drops reduce swelling and help your eye heal after surgery or laser treatment. We often start with frequent dosing and then taper the schedule over several weeks. It is important to follow the taper schedule because stopping steroids abruptly can lead to rebound inflammation. Be aware that steroid drops can raise eye pressure in some patients, which is why we monitor your pressure closely at follow-up visits.
Antibiotic drops are commonly prescribed after incisional surgery to prevent infection during the critical early healing period, and you will typically use them for the first one to two weeks. After many laser procedures, antibiotic drops are not routinely needed, though your surgeon may choose to prescribe them based on your individual situation.
Pressure-lowering drops may still be needed after your procedure, depending on how well your eye pressure responds to the surgery or laser treatment. We will adjust or discontinue these medications based on your pressure readings at follow-up visits.
In some cases, we may occasionally prescribe oral medications such as a carbonic anhydrase inhibitor like acetazolamide to help lower eye pressure in the early post-operative period. Oral steroid pills are rarely needed for routine glaucoma procedures but may be used in specific situations based on your surgeon's judgment.
If you are prescribed acetazolamide, take it with food to reduce the chance of stomach upset, and drink plenty of water throughout the day. Let us know if you have a history of sulfa allergy, kidney disease, or kidney stones, as these may affect whether this medication is safe for you. Contact our office if you experience unusual symptoms like tingling in your fingers or toes, changes in taste, increased thirst, severe fatigue, shortness of breath, significant electrolyte imbalance symptoms, or any allergic reactions. We can adjust your medication if side effects become bothersome.
If you forget a dose, put in the drop as soon as you remember, unless it is almost time for your next scheduled dose. In that case, skip the missed dose and continue with your regular schedule. Never double up doses to make up for a missed one, as this can raise the concentration of medication in your eye and increase the risk of side effects.
If you miss multiple doses or run out of medication before your next appointment, contact our office right away so we can provide a refill or adjust your treatment plan.
Activity Restrictions and Daily Life During Healing
Activity restrictions depend heavily on the type of procedure you had. Laser procedures typically have minimal restrictions, while incisional filtering or tube surgeries require careful limitations to protect the surgical site and promote healing.
After incisional glaucoma surgery such as trabeculectomy or tube shunt implantation, avoid bending over at the waist or lifting anything heavier than ten pounds for the first week. These activities can increase pressure inside your eye and stress the delicate surgical site. If you need to pick something up from the floor, squat down with your knees instead of bending forward.
After laser procedures such as selective laser trabeculoplasty or laser iridotomy, activity restrictions are typically minimal, and most patients can resume normal activities within a day or two. After MIGS procedures, restrictions fall somewhere in between and are often similar to cataract surgery guidelines. Your surgeon will provide specific instructions based on your procedure.
- After incisional surgery, skip strenuous exercise, heavy lifting, and high-impact activities for at least two weeks.
- Avoid straining during bowel movements by staying well hydrated and eating fiber-rich foods.
- Gentle walking is usually safe and encouraged to maintain circulation.
- Do not rub your eye at any time during the healing period, as this can disrupt the surgical site or increase inflammation.
- Avoid dusty or dirty environments in the first week after surgery to reduce infection risk.
- Wait for clearance from our office before resuming gym workouts, running, or yoga.
Try to sleep on your back or on the side opposite your treated eye for the first week. Sleeping face down or on the operated side can put pressure on the eye and disrupt healing, especially if you had a filtering surgery like trabeculectomy.
Using an extra pillow to elevate your head can help reduce swelling and keep you more comfortable at night. If you tend to move around in your sleep, consider placing a pillow on the side of your surgical eye as a gentle reminder.
You can usually shower the day after your procedure, but you must keep water, soap, and shampoo out of your treated eye. Face away from the spray and keep your eyes closed while rinsing your hair. Some patients find it easier to take a sponge bath or have someone help wash their hair over a sink while leaning back.
Avoid soaking your head underwater in a bathtub for at least two weeks after incisional surgery. Pat your face dry gently with a clean towel, and do not rub your eye.
When you can return to work depends on the type of procedure you had and the nature of your job. Many laser patients feel ready to go back within a day or two, while incisional surgical patients may need one to two weeks off, especially if their work involves heavy lifting, dust, or risk of eye injury.
Limit screen time in the first few days if you notice eye strain, dryness, or discomfort. Take frequent breaks and use lubricating eye drops if your eye feels gritty. We will discuss your specific timeline at your first follow-up visit.
Do not drive on the day of your procedure. After that, you may drive only when your vision is subjectively clear and comfortable, you meet legal requirements, and your surgeon has not restricted you. For most laser patients, this is within one to two days, while incisional surgical patients may need to wait one to two weeks or longer.
If you have any doubt about your ability to drive safely, ask a family member or friend for a ride, or contact our office for guidance. It is always better to err on the side of caution and arrange alternative transportation.
After incisional surgery, we will give you a protective eye shield to wear at night for at least the first week. This shield prevents you from accidentally rubbing or pressing on your eye while you sleep. Tape it gently over your closed eye using the method we show you, and remove it each morning. Laser patients typically do not need an eye shield unless your surgeon instructs otherwise.
- Wear sunglasses during the day if you are sensitive to light or if we recommend extra protection.
- Avoid any activities where something could poke or hit your eye, such as contact sports or yard work with flying debris.
- If you wear regular glasses, you can continue using them as long as they do not press uncomfortably on your eye.
Recognizing Normal Healing vs. Complication Warning Signs
Knowing which symptoms are expected and which require immediate attention is essential for a safe recovery. When in doubt, always reach out to our office or our after-hours service.
Mild redness, a scratchy or sandy feeling, and fluctuating vision are all normal in the first week after glaucoma treatment. You may also notice some tearing or sensitivity to bright lights. These symptoms should gradually improve day by day as your eye heals.
Over-the-counter preservative-free artificial tears can help soothe dryness and irritation, but check with us before using any products to make sure they are compatible with your prescribed drops. Avoid using any drops that contain preservatives labeled as redness relievers unless we approve them.
A small amount of clear or slightly pink drainage is normal, especially in the morning. You may wake up with some crust on your eyelashes or a feeling that your lids are stuck together. Gently clean your eyelids with a warm, damp, clean cloth, wiping from the inner corner outward.
Mild tearing is common, but persistent continuous watery leakage after trabeculectomy can be a sign of a wound leak and should prompt a call to our office. If the discharge becomes thick, yellow, or green, or if the crusting increases rather than decreases over the first few days, let us know right away. These changes can be signs of infection and require prompt evaluation.
While most recoveries go smoothly, certain symptoms indicate a possible complication that needs urgent attention. Contact our office immediately, call our after-hours on-call service, or go to an eye emergency department if you experience any of the following:
- Sudden vision loss or a significant, rapid decrease in vision.
- Severe eye pain that does not improve with over-the-counter pain relievers.
- Rapidly worsening pain, redness, and light sensitivity combined with decreased vision, which can signal serious infection such as endophthalmitis.
- New blood layering in your vision or a sudden marked increase in blur, which may indicate bleeding in the front of the eye called hyphema.
- Copious watery tearing or a sudden change in vision with mild discomfort after trabeculectomy, which can suggest a wound leak or hypotony.
- New double vision or a visible or irritating sensation of the implant after tube shunt surgery, which may indicate tube exposure or a position problem.
- Flashes of light, a sudden shower of new floaters, or a curtain or shadow across your vision, which can be signs of retinal detachment.
- High fever or chills along with eye symptoms, which may suggest infection.
- Nausea and vomiting combined with eye pain, which can signal dangerously high eye pressure.
- Any injury to your eye, such as being hit or poked, which requires immediate evaluation.
- Trust your instincts and reach out if something feels seriously wrong.
Call our office during regular business hours if you have questions about your medications, mild discomfort that is not improving, or minor changes in your vision. We can often address these concerns over the phone or schedule an earlier follow-up visit if needed.
For any of the serious warning signs listed above, especially sudden vision loss, severe pain, or signs of serious infection, contact our after-hours on-call service first if possible so we can guide you to the appropriate level of care. If you cannot reach us or if symptoms are rapidly worsening, go directly to an eye emergency department or emergency room. It is always safer to seek urgent evaluation than to wait.
Follow-Up Appointments and Long-Term Monitoring
Regular follow-up is essential to monitor healing and ensure your eye pressure remains at a safe level. The timing and frequency of visits depend on your specific procedure.
The timing of your first follow-up appointment varies by procedure. Many patients who have had incisional glaucoma surgery are seen the day after their operation. After laser procedures, we may check your eye pressure 30 minutes to two hours after treatment, or we may see you the next day or within a few days, depending on our protocol and your individual situation.
During this visit, we will measure your eye pressure, examine the front of your eye under a microscope, and check how well the surgical site or laser treatment area is healing. We will also review your symptoms, assess your vision, and make sure you are using your drops correctly. Bring all your eye drop bottles, including both new post-operative drops and any pre-existing glaucoma medications, along with a written list of all your medications.
Controlling eye pressure is the primary goal of glaucoma treatment, so we will continue to monitor your pressure at every visit even after you have healed. Pressure can change over time, and we need to make sure your surgery or laser treatment is keeping it in a safe range to prevent further damage to your optic nerve.
At each appointment, we will use a device called a tonometer to measure the pressure inside your eye. These readings help us decide whether to adjust your medications, recommend additional treatments, or simply continue monitoring your progress.
Laser procedures often have the shortest recovery, with most patients feeling back to normal within a few days to a week. Surgical recovery is more gradual. After trabeculectomy or tube shunt surgery, it can take four to six weeks for swelling and discomfort to fully resolve, and your vision may continue to improve or stabilize for two to three months.
Minimally invasive glaucoma surgeries, or MIGS, generally fall somewhere in between, with recovery often taking one to three weeks. Your specific timeline will depend on your individual healing response and any other eye conditions you may have.
Even after a successful procedure, some patients need adjustments to maintain healthy eye pressure. For example, after trabeculectomy, we may perform a quick office procedure to release a suture or massage the bleb to improve fluid drainage. If your pressure is still too high, we may add or change your eye drops.
In some cases, a second laser treatment or additional surgery may be needed months or years later. Glaucoma is a chronic condition that requires ongoing care, and we will work with you to create a long-term plan that protects your vision.
If you had trabeculectomy, you will have a filtering bleb, which is a small fluid-filled area under your upper eyelid. This bleb requires lifelong monitoring because it can become infected even years after surgery. If you ever notice new redness, pain, discharge, or vision changes in your treated eye, contact our office promptly, even if your surgery was many years ago.
If you had tube shunt surgery, the implant remains in your eye permanently. Report any new redness, irritation, persistent foreign body sensation, or visible tube exposure to our office. Ongoing follow-up ensures we can address any late complications early and preserve the function of your surgery.
Frequently Asked Questions
Wait at least two weeks before using eye makeup, including mascara, eyeliner, and eye shadow. Makeup particles can introduce bacteria into your healing eye and increase the risk of infection. When you do resume makeup, replace old products with fresh ones and avoid applying makeup to the inner rim of your eyelid.
Yes, a scratchy or gritty sensation is very common after glaucoma procedures and usually improves within the first week or two. This feeling is often due to dryness, mild inflammation, or irritation from sutures. Using preservative-free artificial tears several times a day can help keep your eye comfortable while it heals.
Avoid swimming pools, hot tubs, lakes, and oceans for at least four weeks after incisional surgery to reduce the risk of infection. Chlorinated water, bacteria, and other contaminants can irritate your eye and delay healing. After laser procedures, the timeline may be shorter, but always confirm with your surgeon. Once we confirm that your eye has fully sealed and healed, you can gradually return to water activities.
Some patients can reduce or stop their glaucoma drops after a successful procedure, while others still need one or more medications to keep pressure at a safe level. The goal of surgery is to lower pressure, but it may not eliminate the need for drops entirely. We will adjust your medication plan based on your pressure readings over time.
Temporary blurriness or decreased vision is common right after surgery and often improves gradually over several weeks. However, if your vision becomes significantly worse or you lose vision suddenly, contact us immediately. Sometimes early intervention can address problems like elevated pressure, inflammation, or bleeding before they cause permanent damage.
No, do not rub your eye at any time during the healing period. Rubbing can disrupt the surgical site, increase inflammation, introduce bacteria, or damage delicate new drainage pathways. If your eye itches or feels irritated, use preservative-free artificial tears and gently dab with a clean tissue instead.
