Bausch and Lomb SofPort AO Lens Guide
What the SofPort AO Is
The SofPort AO is a foldable monofocal lens used to replace the eye's natural lens during cataract surgery. The lens has a three-piece design with a silicone optic and PMMA support arms called haptics. It loads through a small incision using a delivery system made for this lens.
Older lenses used a round shape that focused light less evenly. The SofPort AO uses an aspheric shape. The front and back curves are prolate. Per AAO EyeNet (2023), this aberration-free optic does not add or correct corneal spherical aberration. That keeps the eye's optics close to natural. Focus stays steady across most pupil sizes.
The optic is made from soft silicone, and the haptics are made from PMMA. PMMA holds its shape well and helps keep the lens centered after surgery. The optic has a square posterior edge, a design feature that limits how cells can grow behind the lens.
This lens replaces the cloudy lens caused by a cataract and restores clear focus at one chosen distance. Most patients pick distance focus and use reading glasses for close tasks. According to AAO (2024), monofocal lenses like this one give the best uncorrected vision at a single distance, so close-up tasks usually still need help.
How the Aspheric Optic Works
The aspheric shape of the SofPort AO controls how light bends through the lens. The optic keeps even thickness and refractive power across its surface. This makes the lens behave the same way at the center and the edges.
Spherical aberration is a small blur. It happens when light passes through the edge of a round lens at a different angle than the center. Some aspheric lenses try to cancel the cornea's aberration with a negative shape. The SofPort AO does neither. It stays aberration-neutral. It does not add or remove spherical aberration from the eye.
Every lens can shift slightly after surgery. Lenses that try to cancel corneal aberration lose some of that benefit when they tilt. Per AAO EyeNet (2023), aberration-neutral lenses like the SofPort AO are less sensitive to tilt and shift. That makes the optic more forgiving in eyes where lens position may not stay perfect.
Pupil size changes with light, age, and certain medicines. Because the SofPort AO has uniform optical power across its surface, the lens performs predictably whether the pupil is small in bright sun or wide at night. This stability helps with night driving and reading menus in dim restaurants.
Who Tends to Do Well With This Lens
The SofPort AO suits many adults who need cataract surgery and want stable distance vision. It is a monofocal lens, so it sets one focal point. Choice of lens depends on eye anatomy, lifestyle, and willingness to use reading glasses.
People who drive often, watch sports, or spend time outdoors usually want sharp distance focus. A neutral aspheric design like this one tends to give consistent vision in those settings. Reading glasses cover close tasks like phone screens or printed text.
Refractive surgery changes the cornea's shape. It also changes how the cornea handles spherical aberration. Lenses meant to cancel a typical cornea's aberration may not match a post-LASIK or post-PRK eye. The aberration-neutral design of the SofPort AO works with the new shape.
If the lens capsule is weak from past trauma or age, surgeons sometimes place a lens in the ciliary sulcus instead of the bag. The three-piece design of the SofPort AO supports sulcus placement when the bag will not hold the lens safely. That gives the surgeon a backup plan if the bag turns out to be fragile during surgery.
Per AAO EyeNet (2023), bilateral SofPort AO use in a monovision pattern is a non-multifocal way to manage presbyopia. The article reports high rates of spectacle freedom and few night-vision symptoms. In monovision, one eye is set for distance and the other for near. The brain blends the two views. Some patients adapt fast, while others find it harder.
Trade-Offs to Weigh
Every lens choice comes with give-and-take. Knowing the limits of a monofocal lens helps set fair expectations before surgery.
This is a single-focus lens. When set for distance, near tasks like reading or phone use generally need glasses. Some patients pick a near focal point instead, which then requires glasses for distance. Either way, one task usually needs help.
The SofPort AO does not correct astigmatism, which is an oval shape to the cornea that blurs vision at all distances. Patients with notable astigmatism may want to discuss toric lenses or other options that combine cataract removal with astigmatism correction.
Multifocal and extended depth-of-focus lenses spread vision across a wider zone, which can reduce reliance on glasses but may add halos and glare at night. The SofPort AO trades that wider range for steadier night vision and fewer light artifacts. Patients who want broad spectacle independence may prefer one of those other lens types.
Once placed, the SofPort AO power stays fixed. Newer light-adjustable lenses allow fine-tuning after surgery using ultraviolet light. Patients who want a chance to refine their lens power after healing may prefer an adjustable design.
What the Surgery and Recovery Involve
Cataract surgery with the SofPort AO follows the same general steps as any modern cataract procedure. Knowing the timeline helps reduce surprise during recovery.
The eye care team measures the eye's length, corneal curve, and other factors to pick lens power. Drops and tests check overall eye health. Patients usually arrange a ride home, since the eye may feel blurry for several hours after the visit.
Numbing drops keep the eye comfortable, and a mild sedative may help with nerves. The surgeon makes a small opening in the cornea, breaks up the cataract with ultrasound, and removes the cloudy material. The folded SofPort AO slides through the same opening and unfolds inside the lens capsule. Most procedures last around 15 to 30 minutes per eye.
Vision often clears within 1 to 3 days. Final settling and stable vision generally take 4 to 6 weeks. Eye drops to control swelling and prevent infection are part of this period. Mild light sensitivity, watering, or grit feeling may show up during the first week.
Most teams recommend skipping heavy lifting, swimming, and rubbing the eye for at least 1 week. A clear shield protects the eye during sleep for the first few nights. Light walking, watching screens, and most desk work resume quickly.
Possible Issues After Implant
Most patients heal well, but some side effects can appear during or after recovery. Knowing what to watch for makes follow-up easier.
Months or years after surgery, the layer behind the lens can cloud over. The square posterior edge of the SofPort AO is designed to slow this. It limits cell growth onto the back capsule, per FDA labeling. When clouding appears, a quick in-office laser called YAG capsulotomy clears it.
Sometimes the final prescription differs slightly from the target. Glasses, contacts, or a small follow-up laser procedure can fine-tune the focus. The pre-surgery measurement step aims to keep this gap small but cannot remove it entirely.
Cataract surgery can stir up dry eye for a few months. Symptoms include burning, fluctuating blur, and a gritty feeling. Treatment plans often combine lubricating drops with anti-inflammatory drops as needed.
Mild inflammation is part of healing. Prescribed anti-inflammatory drops keep it controlled in most cases. Sudden pain, redness that gets worse, or vision drop after surgery should prompt a same-day call to the surgical team.
When to See a Doctor
Some symptoms after surgery need same-day evaluation, while others are routine. Knowing the difference helps protect vision after a SofPort AO implant.
Sudden vision loss, sharp pain, a curtain over part of the visual field, or a sudden burst of new floaters should trigger a call to the surgical team that day. These signs may point to retinal problems or infection that need quick care.
Worsening redness, thick discharge, or blur that slowly gets worse over a few days deserves an early appointment. These signs may reflect inflammation, dry eye flare, or pressure changes that respond well when caught early.
Standard follow-up visits happen the day after surgery, then around 1 week and 1 month. After that, an annual eye exam tracks general eye health, watches for posterior capsule opacification, and checks for unrelated conditions like glaucoma or macular changes.
Common Questions About the SofPort AO
Most patients see better at night after cataract surgery because the cloudy lens that scattered headlights is gone. The aberration-neutral optic of the SofPort AO tends to keep glare and halos lower than multifocal designs. Some adjustment in the first month is normal as the brain learns the new optics.
Light screen use is usually fine within a day. Long sessions may feel tiring during the first week because the eye is healing and dry eye can flare. Frequent breaks, lubricating drops, and a slightly larger font setting can ease that period.
Once the lens settles in the capsule, light eye contact does not move it. The three-piece design holds position well. Heavy rubbing during the first week of healing should still be avoided to protect the incision and the lens position.
Some patients notice mild halos around lights for the first few weeks. This often fades as swelling settles and the brain adapts. Halos with the SofPort AO tend to be milder than with multifocal lenses because it has a single focal point.
Reading fine print without glasses is uncommon with a distance-set monofocal lens. Most patients use store-bought reading glasses for tasks like prescription bottles, phone messages, and recipe cards. Some patients try monovision, where one eye is set closer, to reduce reading-glass use.
The second surgery is usually similar to the first. The team reviews how the first eye healed, adjusts the lens power calculation if needed, and proceeds in the same way. Many patients feel less anxious the second time because the steps are familiar.
