Preparing for Cataract Surgery
Pre-Surgical Testing One Week Before
According to the National Eye Institute, about a week before cataract surgery, the eye doctor performs measurements to determine the size and shape of the eye. These tests help select the appropriate intraocular lens, or IOL.
The main tests are biometry and keratometry. Biometry measures the length of the eye. Keratometry maps the curve of the cornea. Both results feed into a formula that picks the right lens power.
The pre-surgical tests are not invasive. You rest your chin on a support while a small light shines into your eye. Most tests take only a few minutes per eye.
No drops are required for some tests. Others use mild dilating drops to widen the pupil. The dilation wears off in a few hours. Bright light feels uncomfortable during this time.
According to the American Academy of Ophthalmology Choosing Wisely position, routine pre-operative medical clearance and laboratory testing are not generally required for healthy patients undergoing cataract surgery. Blood tests and EKGs are usually skipped unless a specific medical reason calls for them.
Patients with chronic health conditions may still need clearance from their primary care doctor. Our team can advise on what tests, if any, are needed for your case.
The pre-surgical visit is a good time to review the plan. Our team explains the surgery steps, the lens choice, and the recovery timeline. Bring questions and a notebook.
This visit also covers practical details. The drop schedule, the eye shield, and the day-of-surgery routine all become clear. Understanding the plan reduces stress on surgery day.
Medications and Health Considerations
According to the National Eye Institute, patients should disclose all medications. Some agents that increase bleeding risk may be temporarily held. Bring a complete list of prescription drugs, over-the-counter drugs, and supplements to the visit.
Aspirin and other blood thinners often continue through cataract surgery. Other medications may need to be paused. Our team works with your other doctors on the plan.
Alpha-blockers like tamsulosin are particularly important to disclose. These drugs are used for benign prostate enlargement and other conditions. They can cause intraoperative floppy iris syndrome during cataract surgery.
Knowing about alpha-blocker use allows the surgeon to plan for the floppy iris response. The surgery can still go safely with proper preparation. Patients may not need to stop these drugs before surgery.
Diabetics should optimize blood sugar control before surgery. Better control supports healing and reduces the risk of postoperative complications. Bring your latest hemoglobin A1c result if you have one.
Surgery is not always delayed for elevated A1c alone. Our team plans care based on your overall health, not just one number.
Heart disease, lung conditions, and other chronic issues may need extra planning. Our team coordinates with your primary care doctor or specialists when needed.
Most patients with chronic health conditions still have safe cataract surgery. The brief, outpatient nature of the procedure makes it accessible to many adults.
Pre-Operative Eye Drops
According to the National Eye Institute, surgeons typically prescribe pre-operative antibiotic and anti-inflammatory eye drops. These drops reduce the risk of postoperative infection and inflammation.
The drops usually start one to three days before surgery. Use them on the schedule given by our team. Skipping doses can reduce their effect.
Wash your hands before each dose. Tilt the head back and look up. Pull the lower lid down with one finger to form a small pocket. Squeeze one drop into the pocket. Close the eye gently for one minute.
Do not touch the bottle tip to the eye, eyelid, or fingers. The tip should stay clean. Wait at least five minutes between different drop types.
Store drops at room temperature unless the label says otherwise. Keep the cap tightly closed. Replace the bottle if it becomes cloudy or changes color.
Use a brand new, sterile bottle for surgery preparation. Old bottles from past prescriptions can carry bacteria.
Most patients tolerate pre-operative drops well. Mild stinging is common right after the drop. The feel fades in seconds. A bitter taste in the throat can occur if the drop drains down the tear duct.
Severe redness, itching, or swelling may signal an allergy. Contact our office for any concerning reaction. The team can switch to a different drop if needed.
The Day Before Surgery
According to the National Eye Institute, patients are commonly asked not to eat solid food for at least 6 hours before surgery. This guidance follows standard preoperative anesthesia rules.
Clear liquids like water are usually allowed up to two hours before surgery. Our team gives specific instructions at the pre-op visit. Follow them closely.
Most regular medications continue right up to surgery day. Some pills may need to be paused or adjusted. Our team gives a clear list of which medications to take and which to skip.
Take regular drugs with a small sip of water if needed for the morning of surgery. Bring your medications to the surgery center in case the team needs to verify them.
Avoid eye makeup, lotions, and creams on the face on surgery day. These can interfere with the sterile field around the eye. Plain skin and a clean face support a smoother surgery setup.
Avoid perfume and scented products too. The team often prefers a fragrance-free environment in the operating room.
Wear loose, comfortable clothing on surgery day. A button-up shirt is easier than a pullover. Avoid tight collars or anything that would press on the face during the procedure.
Bring sunglasses for the trip home. Bright light feels uncomfortable after the procedure. The eye is also dilated, which adds to light sensitivity.
A good night's sleep supports a calm surgery day. Avoid stimulants late in the day. Skip alcohol the night before, as it can interfere with sedation.
Most patients feel some nervous tension before surgery. This is normal. The team can answer questions and offer reassurance on surgery day.
Surgery Day Planning
According to the American Academy of Ophthalmology, patients should arrange a ride home. Sedation and dilation can impair driving on the day of surgery. A friend, family member, or rideshare service can fill in.
Driving yourself home is not safe even if you feel alert. Plan for a ride before surgery day to reduce stress.
Bring a photo ID, insurance card, and a list of medications. Wear loose clothing and comfortable shoes. Sunglasses for the trip home are also helpful.
Skip jewelry, valuables, and excess cash. The surgery center has a place for personal items, but a minimal kit is easier to manage.
Arrive at the surgery center at the time given by our team. The check-in process takes some time. Numbing drops, sedation, and dilation all need to be set up before the surgery itself.
The total visit, from arrival to discharge, often takes 2 to 3 hours. The actual surgery is brief, but the prep and recovery add time.
You change into a gown and rest in a recovery area. The team places numbing drops and dilating drops. A mild sedative may be given through an IV. The surgery itself takes about 15 to 30 minutes.
After surgery, you rest until ready to go home. Most patients feel alert within an hour. The eye is covered with a clear shield for protection.
The team gives written instructions before you leave. The drops, the shield, and the activity restrictions are all explained. Bring questions to the discharge talk.
Plan to rest at home that day. Light tasks are fine the next day. Use all drops on the schedule given.
Common Questions About Preparing for Cataract Surgery
Routine medical clearance is not generally required for healthy patients. The American Academy of Ophthalmology Choosing Wisely position supports skipping routine pre-op clearance. Patients with chronic health conditions may still need clearance from their primary care doctor.
