Intraocular Lens (IOL) and Cataract Surgery FAQ

Cataract surgery is a common, safe and effective surgery. Washington Eye’s fellowship-trained surgeons, Drs. Marwa Adi, Howard Weiss, Ken Schwartz, Neil Martin, Dean Flanders, and Lindsay Dawson provide answers to the most frequently-asked questions about cataract surgery and advanced technology lens implants that can correct the vision of cataract patients.

What is a premium or advanced technology lens implant?

These intraocular lens (IOL) implants provide a fuller range of vision at distance and near and are also able to correct astigmatism.  They include Toric IOL, ReSTOR, Symfony, Tecnis Multifocal, and Alcon PanOptix.

Your candidacy for a premium lens during cataract surgery depends on your desire for independence from glasses at a given distance. It also depends on the health of your ocular surface, cornea, and retina. A thorough preoperative evaluation by your surgeon will determine your candidacy.

If I had LASIK, can I have a multifocal implant?

It is possible to have a multifocal lens implant after LASIK, but you have to meet certain criteria. You will require additional preoperative testing that will verify the health of the corneal surface and its regularity before surgery.

Is cataract surgery done in both eyes at the same time?

No. If both eyes need surgery an interval of two to three weeks is advised.

How long does cataract surgery take?

Cataract surgery is performed in a surgical facility and typically takes about 15 – 20 minutes. Your stay at the facility is usually about two hours. You should arrange for someone to drive to and from the facility.

You will arrive at the surgical center approximately an hour before your procedure where you will meet your anesthesiologist, received oral medication to induce relaxation and receive eye drops to anesthetize the eye and dilate the pupil. A thorough cleansing of the eye will also be done.

Once surgery is completed, more drops are applied and a protective plastic shield is placed over the eye.

Once home you should rest and avoid strenuous activities.

Is cataract surgery painful?

Cataract surgery is done with anesthetic eyedrops and mild intravenous sedation. There may an occasional sensation of mild pressure but no pain. Some irritation and tearing are to be expected for a few hours after the surgery.

What is the likelihood of complications from cataract surgery?

Sight threatening complications such as serious infection and bleeding are rare (1/1000). Most complications are otherwise minor and transient such as prolonged inflammation, droopy eyelids, elevated intraocular pressure, and retinal swelling.

Retinal detachment can occur after cataract surgery. Very high myopia (nearsightedness) carries an increased risk for retinal detachment.

Will lens implant surgery cause glare or night vision problems?

Night vision after cataract surgery is a common concern. Unwanted images can occur with all implants. These can take the form of glare or starburst. One should expect halos with multifocal implants. Not infrequently, patients observe a shadow in the outer field of their vision after cataract surgery which typically fades over time.  Your tolerance to halos will influence your decision about multifocal lenses and will be discussed at your preoperative consultation.

What activities can I do after cataract surgery?

You can resume most of your activities within 3 to 5 days after surgery. Heavy lifting and straining are to be avoided for few days. A protective plastic shield is advised at night for three days to prevent inadvertent eye rubbing while asleep. Makeup should be avoided for 5 days. Swimming and hot tubs are not allowed for 2 weeks.

Consult your doctor about specific activities if you are unsure regarding safety.

How often do I need my eyes checked after cataract surgery?

You will be checked the day after surgery. Depending on your particular case, you will be seen one to three weeks later and again three to six months after that.  Annual eye exams are recommended.

Can I go to any eye doctor after surgery?

The surgeon who did the work, or a member of his or her team, should perform the checkup on the day after surgery, and usually the next visit as well. The surgeon may approve subsequent checkups with another doctor, after a consultation with that doctor to ensure familiarity with your case and appropriate care.

Will I have to have cataract surgery again in the future?

Lens implants are typically not subject to deterioration and should last a lifetime.

Some patients will experience a subsequent clouding of the membrane which holds the lens, called the capsule. This clouding will cause blurred vision and is easily fixed with a non invasive laser (YAG laser) beam that creates an opening in the membrane allowing restoration of a clear path for light. This procedure is called a capsulotomy and can be done in our Chevy Chase office.

What about blepharitis and dry eyes in the context of cataract surgery and advanced technology/premium IOL?

Blepharitis and dry eyes are chronic conditions that can affect the surface of the cornea and be exacerbated by surgery. It is critical to optimize the ocular surface before cataract surgery to optimize the outcome. If the ocular surface is suboptimal, multifocal lenses may not suitable for you.

Are advanced technology IOL implants covered by insurance?

Your insurance will cover the cost of cataract surgery, the surgical facility, and the anesthesiologist. You are responsible for costs related to any advanced technology/ premium implants as well as any deductible and co-pays.
