LASIK / PRK
Laser eye surgery is a surgical procedure that uses a cool (non-thermal) beam of light to gently reshape the cornea to improve vision. The laser removes microscopic bits of tissue to flatten the cornea (to correct nearsightedness), steepen the cornea (to correct farsightedness) and/or smooth out corneal irregularities (to correct astigmatism).
The goal of laser eye surgery is to change the shape of the cornea so it does a better job of focusing images onto the retina for sharper vision. LASIK and PRK are two types of laser vision correction. They have a high predictability of the final result with a low incidence of complications. This is because the modern techniques involve a computer’s responsiveness to a predetermined correction of the topographic map of an individual’s cornea and an automated laser for correction.
The laser treatment takes approximately 5-10 minutes per eye.
The eligibility guidelines to be a suitable candidate for laser surgery are:
- Healthy eyes: no glaucoma, infection, cataracts, dry eye or other healing inhibitor
- Age: 21 and older
- Stable vision: your vision must be stable for at least 1 year prior to surgery
- Normal hormone levels: pregnant, nursing, other hormonal changes are ill advised
- Degenerative or autoimmune diseases may adversely affect healing
There are two types of laser eye surgery:
- LASIK: a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. A thin flap in the cornea is created, and then folded back to access and remove some corneal tissue according to specific topographical measurements. The flap is then replaced.
- PRK: a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. No flap is created. The cornea surface is adjusted by removing tissue according to specific measurements so the final corneal surface is corrected.
