The eye capsule is a thin clear layer that surrounds the lens of the eyeball.
Capsulotomy is an eye surgery that requires an incision into the capsule of the eye to gain access to the cataract.
Cutting into the eye capsule must be done with great care to prevent damage. After surgery the eye capsule will hold the artificial lens implant in place for a patient’s entire life so proper healing is extremely important.
Traditionally cataract surgery involves a surgeon to create a small opening in the eye capsule with a specialized needle and then carefully tearing the eye capsule circularly to fit an implant. The tear in the eye should be about 5 to 6mm in diameter and be well-centered for the most successful result.
It is obvious that cutting such small incision in such a sensitive area is very dangerous and is more accurately done using lasers for the cutting. Studies show that intraocular lenses (IOL) are better centered in eye when done with laser incisions. Better centering of the IOL results in better visual outcomes for cataract surgery.
