Questions and Answers About Cataract Surgery in Staten Island, NY

What is a cataract, and how does it affect vision?

A cataract is a clouding of the eye’s natural lens, which sits behind the iris and pupil. As proteins in the lens break down over time, they clump together, reducing the clarity of light passing to the retina. Patients often describe their vision as foggy, hazy, or like looking through a dirty window. Colors may appear faded, and glare around lights, especially at night, becomes more noticeable. An evaluation at Kung Eye Center can confirm whether cataracts are the source of your symptoms.

How does cataract surgery work?

Cataract surgery involves removing the clouded natural lens of the eye and replacing it with a clear artificial intraocular lens (IOL). The procedure is typically performed using a technique called phacoemulsification, in which ultrasound energy breaks the cloudy lens into tiny fragments, which are then gently removed. A new IOL is then placed in the same lens capsule. At Kung Eye Center, Dr. Kung also offers laser-assisted cataract surgery, which uses precise laser technology to perform certain steps of the procedure.

What conditions or vision problems does cataract surgery address?

Cataract surgery is specifically designed to address vision impairment caused by lens clouding. It may help reduce symptoms such as blurred vision, sensitivity to glare, difficulty reading, poor night vision, and frequent changes in your eyeglass prescription.

For some patients, the procedure also provides an opportunity to address refractive errors by choosing a premium IOL, potentially reducing dependence on glasses for distance or near vision. Patients with additional eye health concerns, such as glaucoma or diabetic eye disease, will receive a comprehensive evaluation to determine the most appropriate treatment plan.

Am I a good candidate for cataract surgery?

Most adults with cataracts that meaningfully interfere with daily activities, such as driving, reading, or recognizing faces, may be good candidates for cataract surgery. Your overall eye health, the density and type of your cataract, and the health of your retina and optic nerve are all factors a surgeon will evaluate. Certain systemic conditions or eye diseases may affect candidacy, which is why a thorough pre-surgical examination is essential.

Who is refractive lens exchange (RLE) right for?

Refractive lens exchange, or RLE, is a procedure similar to cataract surgery in which the eye’s natural lens is removed and replaced with a premium IOL, but it is performed before a visually significant cataract has formed. RLE may be a strong option for patients over 40 who are not ideal LASIK candidates, those with significant farsightedness or presbyopia, or individuals who want to proactively reduce their dependence on glasses.

If you are curious about whether LASIK or RLE may better suit your needs, our LASIK self-test can help start that conversation. Candidacy is determined during a personal consultation.

What should I expect during my pre-surgical appointment?

Before cataract surgery, you will undergo a detailed pre-operative examination that includes measurements of your eye’s axial length, corneal curvature, and other structures used to calculate the correct IOL power for your eye. Your pupil will likely be dilated, so plan to have someone drive you home. Dr. Kung and the Kung Eye Center team will walk you through your lens options, discuss your lifestyle and vision goals, and answer every question you have. The goal is to ensure you feel fully informed and comfortable before your procedure day.

How long does cataract surgery take, and what is the day-of experience like?

The surgical procedure itself typically takes between 15 and 30 minutes per eye, though the entire visit, including preparation and a brief recovery period before discharge, generally lasts a few hours. Surgery is usually performed on one eye at a time, with a short interval between procedures. You will receive local anesthesia and a mild sedative to keep you comfortable; most patients are awake but relaxed throughout.

What does recovery from cataract surgery look like?

Most patients notice an improvement in vision within the first day or two following cataract surgery, though full visual stabilization may take several weeks as the eye heals. Mild discomfort, light sensitivity, and some blurring are common in the initial days and are well-tolerated by most patients. You will be prescribed eye drops to support healing and reduce the risk of infection. Most patients return to light daily activities within a few days, though strenuous activity and rubbing the eye should be avoided during the early healing phase.

What factors affect the cost of cataract surgery?

The cost of cataract surgery varies based on several factors, including whether the procedure is performed with standard or laser-assisted techniques, the type of IOL selected, and your individual insurance coverage. Many standard cataract surgeries are covered in part by Medicare and major insurance plans, while premium lens upgrades or laser-assisted steps may involve out-of-pocket costs.

Is cataract surgery safe, and what are the most common concerns patients have?

Cataract surgery is among the most frequently performed surgical procedures in the United States and is considered well-tolerated by the vast majority of patients. As with any surgical procedure, there are risks, including infection, inflammation, and in rare cases, changes to vision. Choosing a surgeon with extensive experience and a meticulous approach significantly supports favorable outcomes.
