Laser Cataract Surgery FAQs


What is Cataract Surgery?

Cataract surgery is a simple procedure with an excellent success record. The clouded natural lens is replaced with an artificial lens called an intraocular lens (IOL). It is done on an outpatient basis with a topical anesthetic that will make it a painless procedure. One eye is done at a time, with a short healing period in between.

After making a very small incision outside your field of vision, your eye surgeon will insert a tiny probe and use ultrasound to break up the clouded natural lens. With suction, the pieces are easily removed, and through the same incision, the IOL is inserted and positioned correctly. You may have a protective shield to wear during sleep for about a week, and your eye surgeon will prescribe eye drops to be used several times each day for several weeks. For best results, it is very important that you follow your surgeon’s post-operative instructions exactly.

What are the risk factors for Cataracts?

By the age of 65, most Americans will have developed cataracts, which occur when your human lens becomes clouded to such an extent that it affects your vision and quality of life. This condition typically occurs with age, but can also result from trauma, disease, and use of certain medications.

Several groups have an increased risk for developing cataracts and eventually need cataract surgery. Examples include:

  • Smokers
  • Diabetics
  • Steroid users
  • Patients who have experienced trauma

If you have cataracts, or plan to have cataract surgery, and you would like to be evaluated, the doctors of Katzen Eye Group would be delighted to assist you. Our doctors are recognized by their patients and colleagues as innovators and pioneers in cataract and intraocular lens (IOL) surgery. Katzen Eye Group doctors were the first in Maryland and among the first in the nation to perform modern day cataract and implant surgery.

Cataract treatment is offered at Katzen Eye Group in Baltimore, at Mercy Medical Center, and in Lutherville-Towson, Maryland. Call us today so we can help you achieve a brighter future!

What are Intraocular Lenses (IOLs)?

When your cataract (cloudy human lens) is removed, it is alike to a camera taking a photograph without a lens; the photo would be blurry. Therefore, anyone undergoing cataract extraction receives a new, man-made lens, called an intraocular lens (IOL), to replace their natural lens.

IOLs are permanent and maintenance free. You cannot feel them, you will never have to clean them, and unlike your natural lens, they stay clear indefinitely. The size, shape, design, material and prescription will be chosen by your doctor especially for you.

What are the different types of IOLs?

After a thorough examination and evaluation, you will be presented various options of IOLs. These IOLs are specially designed for you based upon your doctor’s recommendation and your lifestyle. An IOL counselor will assist you with a detailed explanation of your lens options and answer any questions that you may have.

A Monofocal IOL is a lens that assists patients for distance activities, making patients less dependent on glasses for activities such as driving, going to the movies, and watching TV.

Advanced Technology IOLs (AT IOLs) offer variable distance viewing with greater possibility that glasses or contacts will not be needed. ReStor IOLs provide less dependence at all distances and offer greater freedom from eyewear than traditional monofocal IOLs.

Toric IOLs reduce or eliminate corneal astigmatism and greatly improve distance vision without the need for corrective lenses.

An Accommodating (Crystal) IOL is a revolutionary lens design that changes focus as the patient views objects at varying distances. The Crystalens is controlled by the same eye muscles that would control a natural human lens.

How do I know if I’m a candidate for IOLs?

Cataract surgery is one of the safest and most effective vision correction surgeries available. IOL implantation makes it possible for those with cataracts and age-related eye problems to enjoy the best vision of their lives.

Please contact an ophthalmologist at Katzen Eye Group today, if you’d like to determine your candidacy for cataract surgery with intraocular lenses. Our doctors will evaluate your eyes to ascertain which one of the many intraocular lenses available may be right for you.

Can I have both eyes done in one surgical procedure?

Ophthalmologists will only treat one eye at a time. An average time between surgeries is usually two weeks, but that may depend upon the individual patient and doctor.

How long will the surgery last and is it painful?

In general, cataract surgery will take approximately 10 minutes. You should experience no pain before, during, or after your surgery.

What should I expect during recovery from Cataract Surgery?

During your recovery period after cataract surgery, taking precautions and administering all medications according to your doctor’s instructions will lead to a hasty recovery. The typical cataract surgery patient should return to normal activities within a day or two. Katzen Eye Group staff will answer all of your questions and work with you toward achieving better, clearer, brighter vision.

Patients having their cataracts removed are asked to wear a patch for approximately 6 hours post-operation and a plastic shield to bed, the first night only, to cover and protect the operated eye. You will be asked to use eye drops after surgery.

By following these recommendations and your doctor’s instructions after cataract surgery, you will soon return to activities that might have been previously limited or halted due to previous poor eyesight. If you or someone you know is considering cataract surgery, Katzen Eye Group surgeons are ready to help.
