Laser vision correction in strabismus patients
Strabismus is a condition in which the two eyes are not parallel to each other and do not look in the same direction. In other words, one eye is turned in a different direction than the other eye.
Is it possible to perform laser surgery to treat strabismus?
Depends on the type of strabismus. In accommodative esotropia type laser surgery can be performed which at the same time both corrects the strabismus and removes glasses. This strabismus is an inward strabismus of both eyes. In accommodative esotropia there are usually numbers, pluses (not minuses), and usually high numbers that cause poor vision in both eyes. As a result of poor vision, the eye tries to compensate for the higher numbers and tries to focus.
This increased focus mechanism causes both eyes to go inward and squint inward. As soon as the sight is corrected with glasses or contact lenses, the need to focus and subsequently tostrabismus disappears. Therefore correction with glasses or lenses or a laser to remove glasses increases the strabismus in this type of strabismus. A laser for removing glasses in this type of strabismus is very successful, it lifts the strabismus and also frees the patient from glasses and contact lenses and all the associated meanings.
According to special fitting tests for strabismus patients that include a complete eye examination and additional imaging tests, it is possible to determine the type of strabismus, whether it can be treated with a laser, and whether or not the patient's cornea is suitable for laser surgery to remove glasses.
What are the types of surgery to remove glasses in strabismus patients?
There are several types of laser surgery to remove glasses in accommodative esotropia patients. Dr. Nasser will help you choose the most appropriate surgery for you, based on the type and severity of the glasses problem, eye health, corneal thickness, personal and family history, work, habits, hobbies and expectations:
- Femto-Second LASIK: In Femto-Second LASIK surgery, a suspension of the outer corneal tissue is created using a Femto-Second laser and without the use of surgical knives or blades. The rest of the corneal tissue is then reshaped using another laser and then the sling is put back in place.
- SMILE: In SMILE surgery, a very thin disc-shaped tissue from the cornea is shaped and cut by a Femto laser and without the use of surgical knives or blades. The disc is then removed from the cornea through a small incision. The small incision in the shape of a smiley, gave the operation its name.
- PRK and Trans-PRK: In PRK and Trans-PRK surgery, a laser is used to reshape the cornea but no flap or disc is created. Instead, in PRK surgery, the outer epithelial tissue in the cornea is removed to allow the laser to reach the inside of the cornea. In trance P.R.K. The epithelium is not removed and the laser is applied directly to the cornea, but the epithelium comes off when the surgery is finished. The epithelium will grow back in three to five days on average.
