SBK Vision Correction Surgery: Is It Superior to LASIK and PRK?

SBK Vision Correction Surgery: Is It Superior to LASIK and PRK?

In an ambitious attempt to provide an alternative to LASIK and PRK, surgeons have developed a new type of refractive surgery called SBK, or sub-Bowman's keratomileusis.

Surface Ablation (PRK and Epi-LASIK) Versus LASIK

Surface Ablation (PRK and Epi-LASIK) Versus LASIK

PRK? Epi-LASIK? LASIK? With all the choices on the market today, refractive surgery using an excimer laser is safer and more effective than ever. Find out the differences between these eye-opening procedures.

DLEK and DSAEK Corneal Replacement: On the Cutting Edge of Vision Correction

DLEK and DSAEK Corneal Replacement: On the Cutting Edge of Vision Correction

two exciting new corneal transplant procedures have recently been made available to the public. These procedures are called DLEK and DSAEK. Together, they show the potential to change the lives of millions suffering from diseases and injuries of the cornea, including Fuchs' Dystrophy and corneal edema.

The Importance of Pupil Measurement

The Importance of Pupil Measurement

As you may or may not know, people with very large pupils are generally bad candidates for LASIK and other refractive procedures. As a result, accurate measurement of a patient’s pupils (pupillometry) as a part of the evaluation for refractive surgery is essential.

New Treatment Offers Promise for Keratoconus Patients

One in 1,800 people are diagnosed with an eye condition called keratoconus—a progressive thinning of the outer layer of the eye called the cornea. For most keratoconus patients, rigid contact lenses are the only option to manage thinning and to help correct vision affected by the irregular shape of the cornea.

LASIK Success Depends on the Surgeon

In the beginning, many patients assumed that with the evolution of refractive surgery and improving technology, a good outcome with LASIK surgery would become less dependent on the surgeon, yet the opposite is true.

What is LASEK?

LASEK is a hybrid of FDA approved PRK (Photorefractive Keratectomy) and LASIK (Laser Assisted In Situ Keratomileusis). In this procedure, the surface of the cornea is peeled back, the laser is applied, and the surface layer is then replaced into position.
