Some patients are not suitable candidates for LASIK eye surgery because of inadequate corneal thickness in relation to the prescription needed to correct the vision. Several options for LASIK alternatives are described below.
It is important to understand that one technique isn’t necessarily better than another, but each has certain characteristics that make it more or less effective in certain applications.
Each type of eye surgery below has the same goal, which is to reshape the surface of the cornea and therefore correct the vision. Each of the LASIK alternatives is performed under the outer layer of tissue of the cornea, the epithelium, which is on the surface of the eye itself.
Implantable contacts are recommended for patients who do not qualify for LASIK due to moderate or severe nearsightedness or cases where the cornea is too thin for LASIK.
Monovision LASIK offers presbyopic and pre-presbyopic patients the ability to retain near and distance vision after LASIK surgery with little or no reliance on glasses or contact lenses. If you are over 40, wear bifocals or need reading glasses, you may want to discuss monovision with Corneal Associates.
PresbyLASIK is a type of advanced LASIK that creates multiple power zones on the cornea, allowing for clear vision at multiple distances. Like all vision correction procedures, Dr. Perl will discuss what option is right for you and your visual requirements.
PRK (Photo refractive Keratectomy) is a laser vision correction technique similar to LASIK, except that a laser is used to carry out the entire laser eye surgery operation and no flap is necessary.
