Corneal Transplantation/Intralase enabled keratoplasty (IEK)

Intralase enabled keratoplasty is a new technique performed on patients requiring a corneal transplant whereby damaged corneal tissue is removed and replaced with healthy corneal tissue from a donor.

IEK is an advanced technique of performing full thickness or partial keratoplasty using a computer controlled infrared laser. The technique reduces patient risks compared to traditional transplants and results in quicker vision recovery. Conventional corneal transplants use a hand held blade called a trephine which is used on the cornea to make incisions.The conventional technique requires sutures which remain in the eye for at least 18 months, with a higher chance of increased astigmatism.

 IEK uses a femtosecond laser to precisely cut various shapes resulting in the donor cornea and recipient cornea having an interlocking bond much like a carpenters joint. The pattern of the incisions that the surgeon chooses depends on the pathology in the host cornea.

The advantages of IEK include quicker suture removal, shorter visual rehabilitation time and stronger injury resistant donar- host wounds.

The IEK technique is indicated for patients with keratoconus, pellucid marginal degeneration, corneal scarring (corneal ulcers, trauma) and endothelial diseases like Fuch’s dystrophy.

Intralase enabled keratoplasty is a day procedure performed under general anesthetic. No overnight hospitalization is required and patients will need regular follow ups at Dr Deist’s rooms. Patients can have laser vision correction for residual refractive errors soon after the IEK incisions have healed.
