Other Corneal Procedures
Corneal transplants involve replacing a damaged or diseased cornea with donated tissue to restore or improve a patient’s vision. Technological advances with the Femtosecond Laser have allowed for an improvement in the precision and versatility of techniques in corneal transplantation. The best procedure for you will be determined using the ISA Customized 13-D Diagnostic Set.
Both DSAEK and DMEK transplantation procedures involve replacing only the innermost layers of corneal tissue, instead of the whole thickness of the cornea. This means a smaller incision, a faster visual recovery and a reduced risk of complications.
DALK involves replacing the outer layers of corneal tissue, preserving the innermost corneal layers thus decreasing the risk of donor tissue rejection and/or other eye complications.
Femtosecond Laser Assisted Penetrating Keratoplasty
This is a full-thickness corneal transplant that utilizes the three-dimensional sculpting characteristics of the Femtosecond Laser, allowing for customized grafts that result in safer and more predictable post-operative results.
Corneal Ring Segments
Corneal ring segments are implanted into the corneal tissue to reshape the curvature of the cornea in cases of keratoconus and ectasia for the purpose of improving eyeglass prescription and contact lens tolerance. A Femtosecond Laser is used to sculpt customized corneal channels to allow for implantation.
Corneal Cross Linking
Corneal cross linking involves applying vitamin B2 to the cornea and then exposing it to ultraviolet light to activate a natural process that can potentially help slow the progression of keratoconus.
