Traditional Cataract Surgery

In the weeks before your surgery, your cataract surgeon will order a series of precise measurements called biometry testing. These measurements assess the length of your eye, the curvature of your cornea, and the depth of the front chamber of your eye. The results are used to calculate the correct power for your new IOL.

Advanced formulas use these measurements to predict exactly where the lens will rest inside your eye after it is implanted. Multiple readings may be taken to ensure accuracy, especially if you have had LASIK or other laser vision correction procedures in the past. Getting these measurements right is one of the most important factors in achieving clear vision after surgery.

Most surgical centers require clearance from your primary care provider before cataract surgery, typically within 30 days of your scheduled procedure. This evaluation confirms that you are healthy enough for the mild sedation and the procedure itself. Your medical history and current health will both be reviewed.

Your care team will also review all of your current medications, including blood thinners, diabetes medications, and medications for prostate conditions, since some of these can affect pupil dilation during surgery. Some medications may need to be temporarily adjusted before your procedure. It is important to share a complete list of every prescription, supplement, and over-the-counter product you take so your team can plan appropriately.

Your cataract surgeon will prescribe antibiotic and anti-inflammatory eye drops to begin using two to three days before your surgery. The antibiotic drops reduce the bacterial count on the surface of your eye to lower infection risk. The anti-inflammatory drops help prepare your eye to manage the mild inflammation that naturally follows any surgical procedure.

Following the drop schedule exactly as prescribed matters for your outcome. Your surgeon will provide written instructions with the specific drops, the timing, and the correct sequence. If applying eye drops is difficult for you, ask a family member to help, or ask your care team to walk you through the technique at your pre-operative visit.

Your surgical center will give you specific instructions about eating, drinking, and medications before you arrive. Most centers ask patients to avoid food for several hours before their scheduled time. Continue taking your regular medications with small sips of water unless your surgeon has told you otherwise.

Wear comfortable, loose-fitting clothing and leave valuables at home. Bring your medication list, insurance card, and a photo ID. A responsible adult must drive you home and plan to stay with you for the remainder of the day.

The numbing drops or local anesthetic used during surgery block sensation in the eye, so most patients feel no pain during the procedure itself. A mild pressure sensation or brief awareness of bright light is common and not a cause for concern. After the anesthesia wears off, some patients notice mild soreness or a scratchy feeling for a day or two, which typically responds well to over-the-counter pain relief. If you experience significant or worsening pain after surgery, contact our office promptly, as this should always be evaluated.

Most cataract surgeons schedule each eye separately, with the second procedure typically one to four weeks after the first. This allows your surgeon to evaluate how well the first eye healed and whether any adjustment to lens power or technique would improve the result in the second eye. Performing both eyes on the same day (called immediate sequential bilateral cataract surgery) is performed by some surgeons in select situations, but it is not the standard approach and carries additional considerations that your surgeon would discuss with you.

A small device gently holds your eyelids open during surgery, so blinking is not a concern. The numbing drops also reduce the natural urge to blink. Small involuntary eye movements are something experienced cataract surgeons account for during the procedure. If significant movement occurs, your surgeon will pause and make any needed adjustments before continuing. Complications from patient movement are rare when surgery is performed by an experienced surgical team.

Your cataract surgeon will confirm at your follow-up visit, usually the day after surgery, whether your vision meets the minimum standard required for driving. Most patients receive clearance to drive within a few days. If your other eye still has a cataract, your depth perception may feel slightly off while your brain adjusts to the difference between the two eyes, which is another reason to wait for your surgeon's specific go-ahead before getting behind the wheel.

Once your natural lens is removed, the cataract itself cannot return. However, some patients develop a condition called posterior capsule opacification (PCO), sometimes referred to informally as a secondary cataract. This happens when the thin membrane behind the IOL becomes cloudy over time. PCO is treated with a quick, painless in-office laser procedure called a YAG laser capsulotomy, which takes only a few minutes and typically restores clear vision right away.

Cataract surgery is among the safest elective surgical procedures performed today, with the large majority of patients achieving excellent outcomes without complications. Rare risks include infection, increased eye pressure, swelling inside the eye, and in very uncommon cases, retinal detachment. Your cataract surgeon will review all relevant risks with you during your consultation and take specific precautions throughout the procedure to minimize each one. Knowing what to watch for after surgery, and contacting our office right away if you notice sudden changes in vision, pain, or unusual redness, is an important part of your recovery plan.
