What is LASIK Eye Surgery

Lasik Surgery Treatment and its Side Effects

LASIK surgery first had its roots in a new process developed by Spanish ophthalmologist Jose Barraquer in 1950. In a clinic in Columbia, Barraquer started using the first microkeratome in a procedure that he dubbed keratomileusis.

This would be the surgical part of what would later on become the LASIK eye surgery.

Mani Lal Bhaumik and his fellow scientists followed suit in 1968, when they discovered the Excimer laser which would become the laser to be used in LASIK. Dr. Bhaumik publicized the laser in 1973 and later on acquired a patent for it.

However, the potential for using LASIK in optical surgery would be discovered seven years later by Rangaswamy Srivinasan when he found that excimer laser can sculpt living tissue without any thermal damage to the surrounding area. Following his discovery, Dr. Stephen Trokel then wrote about the potential of using excimer laser in refractive optical surgeries.

It was on June 20, 1989 when U.S. Patent No. 4,840,175 would be granted to Gholam A. Peyman, MD. Gholam’s patent described a method of cutting a flap in the cornea to expose the corneal bed to surgery using the excimer laser. True to Dr. Barraquer’s procedure, the surgery would leave the cornea itself unaltered as it would provide a stable long-term result.

The LASIK Procedure
Before the patient is operated on, the ophthalmologist sedates him with a mild sedative typically Valium. This calms him or her and prepares her for the procedure, which is done with the patient wide awake. The ophthalmologist also drops anesthetic eye drops on the patient’s eye or eyes.

First the eye is immobilized by applying a corneal suction ring. Afterwards the opthalmogist creates a flap using a mechanical microkeratome, or a femtosecond laser microkeratome. The flap is then opened in order to allow the excimer laser to modify the shape of the corneal stroma.

After the laser remodeling is done, the surgeon will then close the flap over the treated eye. With the surgery done, the surgeon then sends the patient on his way with a prescription of antibiotic and anti-inflammatory eye drops for a few weeks.

Advantages of LASIK Surgery
LASIK surgery is said to have several advantages to the previously accepted photorefractice keratectomy. This is because LASIK allows for faster recovery by the patient, because there are essentially no damages to the patient’s cornea. Patients also prefer this refractive laser eye surgery for its effectiveness, as they would rather have a LASIK procedure than having to wear eyeglasses or contact lenses.
