Is it possible to increase the thickness of a cornea?

Unfortunately, there is no way to increase the thickness of your cornea. Corneal thickness is important for laser vision correction because in order to correct your vision, we need to sculpt/reshape the cornea with the laser - doing this results in the removal of corneal tissue. Larger glasses prescriptions require larger amounts of sculpting, and consequently more tissue removal. If your cornea is naturally thin, removing more tissue with LASIK or PRK puts the cornea at risk for warpage and irregular astigmatism. These changes can ultimately lead to poor vision and may require corneal transplantation.There are other options to reduce your dependence on glasses and contact lenses, such as clear lens exchange or implantable contact lenses. It is important to discuss the risks and benefits of these procedures with your eye doctor. That way, you can decide on the best option for you that fits your lifestyle and visual demands.
