Revolutionizing Vision: Exploring Modern Corneal Transplant Options

In the realm of ophthalmology, breakthroughs in corneal transplant surgery have paved the way for enhanced vision and quicker recovery times. Dr. Jeffrey Liu, a specialist at the Cornea Center, Peninsula Laser Eye Medical Group, is at the forefront of these advancements. Offering an array of cutting-edge procedures, Dr. Liu aims to improve the quality of life for patients in Northern California and the Bay Area.

Corneal transplants become necessary when diseases, infections, or injuries compromise the cornea, leading to diminished vision or discomfort. When traditional treatments prove ineffective, Dr. Liu steps in with four distinct types of corneal transplants, each tailored to specific conditions.

Descemet’s Membrane Endothelial Keratoplasty (DMEK) is designed for the damaged inner layer of the cornea, offering a smoother surface and faster healing. Though associated with a higher risk of graft detachment, the benefits, including improved visual acuity, make it a compelling option for conditions like Fuch’s dystrophy.

Descemet’s Stripping Automated Endothelial Keratoplasty (DSAEK), similar to DMEK, involves a partial-thickness transplant. With a slightly thicker donor tissue, DSAEK provides added stability, reducing the likelihood of additional procedures post-surgery. While visual acuity may be slightly less sharp than with DMEK, the results still significantly improve vision.

Penetrating Keratoplasty (PKP) replaces all layers of the central cornea, making it the preferred choice for corneas with substantial scarring. The healing process involves sutures and may take 6 to 12 months, with patients eventually needing glasses or contact lenses for optimal vision.

Deep Anterior Lamellar Keratoplasty (DALK) replaces outer corneal layers while preserving the innermost layer. Ideal for advanced cases of keratoconus, DALK offers a lower risk of graft rejection and infection compared to full-thickness transplants, with a similar healing time.

The benefits of DMEK and DSAEK are clear—stronger corneal integrity, smaller incisions for faster recovery, and reduced risk of graft rejection. These procedures mark a departure from the traditional corneal transplant, which often required extensive healing periods and multiple sutures.

Corneal tissue for transplantation is sourced from Eye Banks, ensuring rigorous quality standards are met. Dr. Liu emphasizes that the color of the donor eye is irrelevant, as only the clear cornea is replaced. Fortunately, there is no waitlist for donor tissue, and it can be stored for several days before use.

With his extensive training in corneal transplantation, Dr. Jeffrey Liu is at the forefront of these revolutionary procedures.
