LASIK & Cataract FAQ's

What is ophthalmology?

Ophthalmology is the medical specialty concerned with the anatomy, function, and diseases of the eye. An ophthalmologist is a medical doctor who specializes in eye and vision care -- providing the full spectrum of eye care, from prescribing glasses and contact lenses to complex and delicate eye surgery.

What is laser vision correction?

Laser vision correction is a procedure that improves your vision by permanently changing the shape of your cornea (the clear covering of the front of the eye) with a laser. Often referred to as LASIK (an acronym for the medical term laser assisted in-situ keratomileusis ), it is the most commonly performed type of laser procedure and is an effective treatment for a wide range of vision problems, such as nearsightedness, farsightedness and astigmatism.

How long does a LASIK procedure take?

LASIK is an outpatient procedure that takes less than 15 minutes to complete. You should expect to be in the office for approximately 60-90 minutes. Most patients are able to return to work--and resume most of their normal daily activities--the day after the procedure.

How quickly will my vision improve after LASIK?

Your vision usually improves immediately after treatment. You will typically notice dramatic visual results within the first 24 hours following the procedure, but your vision can continue to improve for the next six months. (Although you may experience fluctuations in your vision for several days after the procedure, this will usually stabilize after the first week.)

What are the risks of LASIK?

As with any medical procedure, LASIK does have risks. However, the incidence of complications has been documented in a number of clinical studies to be low. Some potential complications can include dryness, increased sensitivity to light, night glare or haloes, irregular astigmatism, under correcting or over correcting, complications in making the surgical flap and loss of best-corrected vision. These complications occur in less than one percent of procedures. Dr. Petermann will discuss any possible risks with you during your examination and determine if LASIK surgery is appropriate for you and your specific vision needs.

What are cataracts?

Many factors, such as aging can cause cataracts, a clouding of the normally clear lens of the eye. It can be compared to a window that is frosted or yellowed. A thor­ough examination by one of our doctors can detect the presence of a cataract. Common symptoms are glare when driving at night and difficulty reading. If cataracts are present, surgery may be recommended. During the sur­gery, Dr. Petermann removes the natural lens and replaces it with a lens implant that is de­signed to provide you with clearer vision.

What are Premium Lens Implants?

Premium lens implants are used in conjunction with standard cataract surgery. Dr. Petermann uses special lenses such as the Restor®, Re­zoomTM and crystalens® to help with distance, near and intermediate vision. He also can use techniques and lenses to eliminate astigmatism. These surgeries help patients achieve greater independence from glasses.
