How much is lasik surgery nyc are thin, clear semi-circular plastic ring inserts that can be used to treat moderate to severe nearsightedness and may postpone the need for a corneal transplant. During this outpatient procedure, the ring inserts are placed into the outer areas of your cornea, changing the curvature and reducing the cone-like distortion caused by keratoconus. They can also be exchanged or removed, allowing them to be modified over time for vision needs that change. Unlike laser eye surgery, the corneal tissue remains intact, making it less likely to experience complications such as dry eyes and halos.
Are Intacs good for keratoconus?
During the procedure, your doctor will make a small opening in the cornea and then insert one of the Intacs rings into the cornea. The doctor will then close the opening. Depending on the severity of your keratoconus, you may require more than one Intacs implant in order to achieve good vision. Once the inserts have been properly placed, your physician will suture the small opening in your cornea.
In a study on keratoconus, 1 or 2 Intacs segments oriented by preoperative corneal topography were found to be effective in decreasing corneal steepening and astigmatism and improving best-simulated spherical visual acuity (BSCVA). The thicker segment was positioned in the area corresponding to the steeper part of the kerataconus cone, predominantly inferiorly, to lift and flatten the cone. The thinner segment was positioned in the opposite half of the cornea to counterbalance the thicker portion and produce a more uniform flattening effect.
