Dr. William Boothe & Epi-LASIK Surgery
Dr. Boothe Discusses Epi-LASIK Surgical Procedure
Epi-Lasik (Epithelial Laser in Situ Keratomileusis) is a relatively new technique for correcting refractive error and restoring clear vision for patients. Distinct from conventional LASIK, Epi-Lasik is a delicate procedure that is ideal for patients with thin corneas, a condition that increases patient’s risk of complications in conventional LASIK surgeries.
While both LASIK and Epi-Lasik share many similarities, some importance differences include creating a thinner tissue flap in Epi-Lasik, as well as omitting the use of alcohol to separate the flap, which reduces the risk of damaging epithelial cells. In traditional forms of LASIK, an incision in the cornea is made using a sharp blade known as a microkeratome. Alcohol is then used to gently loosen the corneal layer, creating a flap that can be folded back on a hinge. An excimer laser then shapes the exposed tissues beneath to correct refractive error as needed.
Epi-Lasik procedures, however, do not involve creating a complete corneal flap. Rather, the surgeon makes a small incision in the cornea’s outermost layer, the epithelium, using a blunt, plastic oscillating blade. Instead of using alcohol, the instrument is used to separate the thin tissue and fold it back. This method allows for a shallow corneal incision that avoids cutting too deeply for patients with exceptionally thin corneal tissue. This nuance also makes Epi-Lasik ideal for people with flatter corneas.
Once the corneal tissue beneath has been excised to help refocus light on the retina and improve visual clarity, the epithelial layer is carefully restored to its original place. A special oxygen-permeable contact lens is used to keep the epithelial flap in place while it heals. To prevent external trauma, the patient’s eyelid will be bandaged.
Dr. William Boothe
Performing Epi-Lasik procedures requires a highly skilled and experienced surgeon. Using advanced laser systems, Dr. William Boothe has successfully restored clear eyesight for thousands upon thousands of patients at his world-class facility near Dallas, Texas. Dr. Boothe is a staunch advocate for the laser technologies at his practice, always making sure his patients reap the benefits of the most advanced breakthroughs that science has to offer.
After the Procedure
Within three days of the surgery when the healing has taken place, Dr. Boothe may remove the protective lens. By this time, most patients experience 20/20 or 20/40 vision, but may continue to see improvements for up to 6 months. Patients can usually resume driving about one week after the procedure.
As with any surgical procedure, Epi-Lasik carries some risk of complications, particularly with the healing of the epithelial flap. Compared with LASIK, Epi-Lasik procedures have higher risk of infection and flap dislodgement. Side effects may include glares, starbursts, halos, and over or under correction of eyesight. The patient may also develop astigmatism if the epithelial tissue removed is uneven.
Ultimately, the improvement and quality of vision following an Epi-Lasik procedure will depend on how well the cornea heals. It is important to follow aftercare instructions carefully, never missing medications or eye-drops prescribed by Dr. William Boothe.
