LASIK Laser-Assisted In-Situ Keratomileusis is an excellent option for the treatment of nearsightedness, farsightedness and/or astigmatism. It offers many people the opportunity to greatly reduce or in many cases eliminate the need for eyeglasses or contact lenses. While most patients are eligible for LASIK, certain individuals may have less risk or better outcomes with an alternative vision correction procedure.
You may be considered for other vision correction options if you have:
- High myopia (nearsightedness) or astigmatism (differently shaped cornea)
- Relatively thin corneas
- History of dry eyes
- Previous eye surgery: radial keratotomy (RK), LASIK or a corneal transplant
- Greater than average risk of future eye injury due to job or hobbies
- A cataract, which is better managed by cataract surgery
- Medical conditions that may be less safely treated by LASIK: herpes simplex eye infections, corneal scars or recurrent erosion syndrome
At your initial exam, your Surgical Specialist will evaluate your eyes and determine which procedure is best for you.

PRK Photorefractive Keratectomy was the first excimer laser vision correction treatment and remains the preferred technique for those who may not be optimal LASIK candidates. Like LASIK, PRK reshapes the cornea with a precise excimer laser beam, but is distinct in that it does not involve the creation of a corneal flap. Instead, the outer layer of the cornea, the epithelium, is removed and allowed to naturally regenerate in a few days. PRK is a treatment option for patients with high myopia (nearsightedness) and/or astigmatism, thin corneas, treated dry eyes, prior RK, LASIK or corneal transplants, patients with a high risk of ocular injury and medical conditions that may make them less suitable for treatment by LASIK.
LASEK Laser Sub-Epithelial Keratomileusis is a procedure that ¬¬combines aspects of PRK and LASIK. Like LASIK and PRK, LASEK reshapes the cornea with a precise excimer laser beam, but is distinct from LASIK in that it does not involve the creation of a corneal flap and from PRK in that the epithelium is preserved and replaced at the end of surgery. LASEK is a treatment option for patients with nearsightedness, farsightedness and/or astigmatism. It is not as commonly performed, compared to LASIK or PRK, which offer similar results.
AK Astigmatic Keratotomy is a procedure used to reduce astigmatism, a condition in which the shape of the cornea is oblong rather than round, producing visual distortion. AK works by reshaping the cornea through tiny peripheral incisions, created with either a diamond blade or femtosecond laser, into a more spherical shape. AK is a treatment option that may be used alone or in conjunction with other vision correction procedures.
ICL An Implantable Collamer Lens, sometimes called an Implantable Contact Lens, is a flexible gel-like lens that is permanently placed inside the eye. It corrects refractive errors without tissue removal or lens extraction. ICL's are typically used to treat higher degrees of nearsightedness and farsightedness in patients who may not be good candidates for LASIK.
Speciality IOLs Accommodating and Multifocal Intraocular Lenses are appropriate for cataract surgery patients, who because of their lifestyle, job, or hobbies would like a more natural range of vision than that offered through a standard monofocal IOL. If you require treatment for cataracts, you and your doctor may want to discuss the risks and benefits of these lens options to see if they are right for you.
