Cataract Surgery in Walnut Creek, CA
Small-incision cataract surgery with your choice of standard or premium lens implants, performed by a board-certified ophthalmologist with cornea and refractive training.
Cataract surgery replaces the eye's clouded natural lens with a clear artificial lens implant. It is a fifteen-minute outpatient procedure done with numbing drops and light sedation at Aspen Surgery Center, and most patients see better within days. Vahid Feiz, MD offers the full range of implants — monofocal, toric, extended-depth-of-focus, and full-range lenses from Alcon, Johnson & Johnson, and Bausch + Lomb — so the result can be tailored to how you actually use your eyes. Medicare and medical insurance cover the procedure with a standard lens.
Signs it may be time
- Glare and halos from oncoming headlights; avoiding night driving
- Colors look faded or yellowed; needing more light to read
- Frequent glasses prescription changes that stop helping quickly
- Blurry or filmy vision even with the right glasses
A cataract does not harm the eye by being left alone, so the timing is yours. Once it affects your daily life, surgery is the fix — no drops, glasses, or diet slow a cataract down.
What actually varies between surgeons
The operation itself is highly standardized. What differs is the planning: precise measurements of the eye, the right lens-power formula (especially after prior LASIK or with unusual corneas), management of astigmatism, and matching the lens technology to your life. That planning is where Dr. Feiz's cornea and refractive background shows. Modern cataract surgery is effectively a refractive procedure — a chance to correct your prescription for good.

| Toric | Corrects astigmatism | Readers; no distance glasses | Out-of-pocket upgrade |
| Vivity, TECNIS PureSee (EDOF) | Distance plus intermediate — dashboard, computer, kitchen | Occasional readers for fine print | Out-of-pocket upgrade |
| PanOptix, TECNIS Odyssey, enVista Envy | Full range: distance, intermediate, and near | Most patients glasses-free | Out-of-pocket upgrade |

What to expect
- Consultation and measurements — dilated exam, optical biometry, corneal topography, and a conversation about how you use your eyes. You leave with a written lens recommendation and cost.
- Surgery day at Aspen Surgery Center — about two hours door to door, roughly fifteen minutes of surgery. The cloudy lens is removed through a small incision using the Alcon Centurion phacoemulsification system, and the new lens implant is placed. Someone drives you home.
- Day after — Dr. Feiz checks the eye at the Walnut Creek office. Most patients already notice brighter, clearer vision.
- Second eye — typically one to two weeks later.
- One month — final check and, if you want one, a glasses prescription for any remaining needs.
Complex cataracts
Dr. Feiz regularly manages cataracts in eyes that are not routine: prior LASIK, PRK or RK; Fuchs' endothelial dystrophy, where a combined cataract and DMEK may be planned; very dense cataracts; small pupils; pseudoexfoliation; and eyes with previous trauma. If another surgeon has described your case as complicated, a cornea specialist is often the right second opinion.

Frequently asked questions
When should I have cataract surgery?
When the cataract interferes with things you want to do — driving at night, reading, recognizing faces, glare in sunlight — and glasses no longer fix it. There is no benefit to waiting until a cataract is 'ripe'; very dense cataracts are actually harder to remove.
Is cataract surgery covered by Medicare and insurance?
Yes. Medicare and essentially all medical insurance cover cataract surgery with a standard monofocal lens implant, the surgeon's fee, and the facility fee, less your deductible or copay. Premium lens implants are not covered and are paid out of pocket.
Where is the surgery performed?
At Aspen Surgery Center. The procedure is outpatient, takes about fifteen minutes, and you go home the same day.
Is it painful?
No. It is done with numbing drops and light sedation. You are awake but relaxed, and most patients feel pressure at most.
How long is recovery?
Most patients see noticeably better within one to three days and resume normal activities, including driving, within a few days. You will use drops for about three to four weeks and avoid heavy lifting and eye rubbing during the first week.
Will I need glasses afterward?
That depends on the lens you choose. A standard monofocal lens gives sharp vision at one distance and you will use reading glasses. Extended-depth-of-focus and full-range lenses can reduce or eliminate glasses for most tasks, and toric lenses correct astigmatism. See lens implant options.
Can I have cataract surgery if I had LASIK years ago?
Yes, though the lens power calculations are more complex after LASIK or PRK, and surgeons who do not do this regularly can leave patients with an unexpected prescription. As a refractive and cornea surgeon, Dr. Feiz handles these cases routinely using post-refractive formulas and modern measurements.
Are both eyes done the same day?
Usually the second eye is done one to two weeks after the first, which lets us confirm the result of the first eye and fine-tune the plan for the second.
What are the risks?
Cataract surgery is one of the safest operations in medicine, with a serious complication rate well under 1%. Infection, retinal detachment, swelling, and lens capsule issues are rare and treatable. A mild clouding behind the implant — posterior capsule opacification — can develop months or years later and is cleared in minutes with an office YAG laser capsulotomy.
