Advances in Cornea Transplantation

Cornea Transplantation in Singapore

A corneal transplant is the replacement of a diseased or scarred cornea with a donor cornea.

With the advancement in technology, there are other ways to replace a diseased or scarred cornea, compared to the common surgical approach like penetrating keratoplasty (PK), which is also known as full-thickness corneal transplantation.

We specialise in the following types of cornea transplantation in Singapore:

  • Lamellar (Partial) Keratoplasty (LK)
  • Anterior Lamellar Keratoplasty (ALK)
  • Posterior Lamellar Keratoplasty (PLK) / Endothelial Keratoplasty (EK)

Lamellar (Partial) Keratoplasty (LK)

Lamellar (partial) Keratoplasty (LK) refers to the replacement of selective parts of the cornea that are diseased, provided the disease has not extended to all the layers of the cornea.

Benefits of Lamellar (Partial) Keratoplasty (LK)

1. Lower risks of rejection and failure: Compared to the conventional surgical approach Penetrating Keratoplasty (PK), there is longer graft survival and significantly lower risks of allograft rejection and failure in LK procedures.

2. Better visual outcomes: There are less irregularity and astigmatism. Studies have also shown that LK visual outcomes are comparable to those of PK surgery.

Anterior Lamellar Keratoplasty (ALK)

Anterior Lamellar Keratoplasty (ALK) is performed for patients with diseases involving the upper portion of the cornea like

  • Anterior Scars
  • Anterior Dystrophies
  • Keratoconus
  • Infectious Keratitis

Benefits of Anterior Lamellar Keratoplasty (ALK)

1. Lower risks of rejection and failure: Compared to the conventional surgical approach Penetrating Keratoplasty (PK), there are significantly lower risks of allograft rejection and graft failure in ALK procedures.

2. Better visual outcomes: There are less irregularity and astigmatism. Studies have also shown that ALK visual outcomes are comparable to those of PK surgery.

3. Greater wound strength: ALK is an extraocular procedure, which enables greater wound strength.

Posterior Lamellar Keratoplasty (PLK) / Endothelial Keratoplasty (EK)

In cornea diseases where the innermost layer of the cornea (endothelium) is affected, only the innermost layer of the cornea may be replaced.

Posterior Lamellar Keratoplasty / Endothelial Keratoplasty (PLK) is performed for patients with certain degenerative diseases like

  • Fuch’s Endothelial Dystrophy
  • Bullous Keratopathy

The surgery is performed through smaller incisions. The cornea graft can also be secured in place without the need for stitches. The new method is known as Descemet’s stripping automated endothelial keratoplasty (DSAEK).

Benefits of Posterior Lamellar Keratoplasty (PLK) / Endothelial Keratoplasty (EK)

1. Better visual outcomes: There is less irregularity and astigmatism. Studies have also shown that PLK / EK visual outcomes are comparable to those of PK surgery.

2. Faster visual recovery: The patient’s eye feels more comfortable after PLK / EK. The patient also recovers faster due to the use of semi-automated microkeratomes, which creates a smoother dissection plane, reduces interface irregularity, and improves the visual outcome.

3. No suture-related problems: As the donor graft is attached without sutures, there will not be any suture-related problems.

4. Greater wound strength: PLK / EK is a minimally invasive cornea transplant procedure so there is greater wound strength.

Why Choose Lang Eye Centre for Cornea Transplantation in Singapore?

Experienced Doctor in Cornea Transplantation

Our world-renowned Senior Ophthalmologist Dr. Leonard Ang has extensive experience in refractive surgery, having trained with the top refractive surgeons at prestigious eye centres around the world, including the Kyoto Prefectural University of Medicine in Japan, and Harvard Medical School, Massachusetts Eye and Ear Infirmary in USA.

He underwent specialised training at Harvard Medical School in artificial cornea transplantation (Boston keratoprosthesis). He performed the first series of Boston keratoprosthesis transplantations in Singapore and South East Asia, and has helped to restore the vision of many local and international patients with complex cornea diseases. He also performed the first series of Paediatric Boston keratoprosthesis transplantations in Singapore and South East Asia for blinding childhood cornea diseases.
