What to Expect Before, During, and After Cataract Surgery

If you've been told you have a cataract that's ready for surgery, you may have a lot of questions. What does the procedure actually involve? Will it hurt? How long is the recovery? At Orchard Ophthalmology in Farmington Hills, MI, Dr. Mavis M. Gappy, M.D. walks every patient through the process so there are no surprises. Here's a complete guide to what you can expect.

Before Surgery: Your Pre-Operative Evaluation

Before scheduling cataract surgery, Dr. Gappy will perform a thorough pre-operative examination. This visit has two main goals: confirming that cataract surgery is the appropriate treatment for your vision loss, and gathering precise measurements of your eye to select the correct intraocular lens (IOL) implant.

During this evaluation, we will measure the length of your eye and the curvature of your cornea using optical biometry — a painless, non-contact scan that takes only a few minutes. We will also evaluate the health of your cornea, retina, and optic nerve to make sure there are no other conditions that could limit your visual outcome, and discuss IOL options with you, including monofocal lenses, toric lenses (correcting astigmatism), and premium multifocal or extended-depth-of-focus lenses.

You will be asked to stop wearing contact lenses for several weeks before this measurement appointment, as contacts change the shape of the cornea and can affect accuracy.

The Night Before and Day of Surgery

Cataract surgery is performed on an outpatient basis — you will go home the same day. You'll be asked to avoid eating or drinking anything after midnight the night before surgery, arrange for a driver (you will not be able to drive yourself home), use your prescribed pre-operative eye drops as directed, and wear comfortable, loose clothing without makeup or jewelry.

On the day of surgery, you'll check in at the surgical facility. The nursing staff will place dilating drops and anesthetic drops in your eye, and you may receive a mild oral sedative to help you relax. You will be awake during the procedure, but your eye will be completely numb and you will feel no pain.

During Surgery: The Procedure Step by Step

Modern cataract surgery — called phacoemulsification — typically takes between 10 and 20 minutes per eye. Here's what happens:

A tiny incision (about 2–3 mm) is made at the edge of the cornea. This incision is self-sealing and requires no stitches in most cases. A small opening is made in the capsule — the thin membrane that surrounds the natural lens. An ultrasonic probe is then inserted, vibrating at high frequency to break the clouded lens into tiny fragments that are gently suctioned out. The capsule is left in place to serve as a cradle for the new IOL, which is folded, inserted through the same small incision, and unfolds inside the eye to take its permanent position.

The entire procedure is performed under an operating microscope. Most patients describe hearing sounds and seeing bright lights during the procedure, but find it surprisingly quick and comfortable.

Immediately After Surgery: Recovery Room

After the procedure, you'll rest briefly in the recovery area. Most patients are discharged within 30 to 45 minutes. Your eye will be covered with a shield, and you'll receive written instructions along with your post-operative eye drops.

Common sensations in the first 24 hours include mild scratchiness in the eye, slight blurring as the eye adjusts to the new lens, light sensitivity, and mild redness. These are all normal and temporary. Serious pain is not normal — if you experience significant pain, sudden vision loss, or increasing redness, contact our office immediately.

The First Week: Post-Operative Care

Your most important job in the first week is using your eye drops correctly. You'll typically be prescribed an antibiotic drop to prevent infection and an anti-inflammatory drop to reduce swelling. These drops are usually used several times per day and tapered over the first few weeks. Do not skip doses.

During the first week, you should also avoid rubbing or pressing on the operated eye, wear your eye shield at night for at least one week, avoid swimming and getting water directly in the eye, avoid dusty environments, and avoid heavy lifting (greater than 10–15 pounds).

Vision Recovery: What to Expect Week by Week

Most patients notice a dramatic improvement in vision within the first 24 to 48 hours, though vision may fluctuate during the first week. By the end of the first week, the majority of patients have achieved their best corrected visual acuity. Full healing of the corneal incision takes approximately four to six weeks. New glasses — if needed — are typically prescribed six to eight weeks after surgery, once your prescription has stabilized.

Life After Cataract Surgery

For the vast majority of patients, cataract surgery is transformative. Colors are vivid again. Night driving becomes manageable. Reading and distance vision improve significantly. The new IOL is permanent — cataracts cannot grow back on an artificial lens.

Occasionally, patients develop a secondary clouding of the lens capsule (posterior capsule opacification, or PCO) in the months or years after surgery. This is treated quickly and painlessly with a laser procedure called a YAG capsulotomy, performed in the office.
