Corneal Transplant Outcomes Could Be Changed By Femtosecond Laser

A new laser known as femtosecond laser could change the face of the corneal transplant outcomes.


A pilot program called the Femtosecond laser assisted keratoplasty or FLAK was done for two years. This study involves full thickness corneal transplants using ultrafast or femtosecond laser.

Researchers at Kellogg were the first to use the femtosecond laser for the industrial purposes. It was then when it was considered to have a great potential for eye surgeries that traditionally is required for a surgical blade or knife. Through the joint efforts of the faculty from kellogg and the U-M college of Engineering, the femtosecond laser was further developed, and is widely used to refractive surgery.

“The main advantage of this laser is that it allows the surgeon to focus the laser energy at a particular depth and then rapidly cut the tissue at that depth without causing any additional injury to the surrounding tissue,” says Shahzad I.Mian, M.D., assistant professor in the Department of Ophthalmology and Visual Sciences at Kellogg, and principle investigator of the FLAK study. “It also allows the surgeon to pattern these cuts into shapes – such as a mushroom, a top hat or a zig zag – that allow for better customized overlap between the donor’s corneal tissue and the patient’s corneal tissue.”

Because of the speed and precision of the femtosecond laser, the doctors are hoping the patients will have better vision, faster recovery of vision, and stronger wound construction, which will allow the patients to more resistant to injury in future.

    My third corneal transplant is failing after a couple of years. I am considering having a fourth transplant but am becoming more and more convinced it will also result in rejection. Is there any new research or evidence of new procedures that may give me hope of a better outcome? Ant information is very much appreciated,
