Severe Dry Eyes

What is Severe Dry Eye? The eye depends on the flow of tears to provide constant moisture and lubrication to maintain vision and comfort. Tears are a combination of water, for moisture; oils, for lubrication; mucus, for even spreading; and antibodies and special proteins, for resistance to infection. These components are secreted by special glands [Read More]

Radial Keratotomy (RK)

Radial Keratotomy (RK)? Radial Keratotomy (RK) is a surgical procedure used to decrease nearsightedness. During the procedure, radial incisions are made in the cornea of the eye with a highly precise diamond blade set to a particular depth. The number of incisions and their location is determined by the degree of nearsightedness. These incisions allow [Read More]


What is Ortho-Keratology? Orthokeratology (ortho-k) is the fitting of specially designed gas permeable contact lenses that you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye (cornea) so you can see clearly the following day after you remove the lenses when you wake up. Ortho-k lenses are prescribed [Read More]

Post-LASIK Ectasia

Lasik (laser eye surgery) Surgery Complications LASIK, a form of refractive surgery, is an option for vision correction which reduces the need for glasses or contact lenses. Simply put, LASIK reshapes the cornea by using a laser. In rare cases, many years (average 9 years) after laser eye surgery the cornea can thin. This is [Read More]


What is Keratoconus? The cornea is the window of the eye. Light travels through the cornea past the lens to the retina and then the brain to form a visual image. The normal corneal surface is smooth and aspheric, i.e. round in the center, flattening towards its outer edges. Light rays passing through it move [Read More]

Irregular Astigmatism

What is Irregular Astigmatism? Astigmatism is a common eye condition that’s usually corrected by eyeglasses, contact lenses, or surgery. Irregular astigmatism creates distortion in your vision and may not be correctable with spectacles, as compared to medically necessary contact lenses. Often, irregular astigmatism [Read More]

GVHD- graft-vs-host-disease

What is GVHD- graft-vs-host-disease? Ocular Graft Versus Host Disease (GVHD) occurs in patients who have undergone allogenic hematological stem cell transplantation. It can occur in patients who have acute or chronic GVHD, though it is more common in patients with the chronic form. Approximately 40-90% of patients with chronic GVHD will develop ocular symptoms. Ocular [Read More]

Corneal Transplant

What is a Cornea Transplant? A cornea transplant, which replaces damaged tissue on the eye’s clear surface, is also referred to as a corneal transplant, keratoplasty, penetrating keratoplasty (PK), or corneal graft. A cornea transplant replaces central corneal tissue, damaged due to disease or injury, with healthy corneal tissue donated from an eye bank. An [Read More]

Corneal Scar Tissue

What is Corneal Scar Tissue? Cornea scar tissue is defined as any opacity on or within the cornea surface of the eye. The normal cornea is a clear window that allows transmission of light rays to pass through the eye and reach the retina (nerve layer) of the eye to create vision in the brain. [Read More]
