Scleral Lenses are a special type of contact lenses that covers more of the eyes and allows for increased comfort.
Who Benefits from Scleral Lenses?
Lots of patients have tried contact lenses in the past but found them too uncomfortable or difficult to wear. Scleral contact lenses offer extra stability and a higher level of comfort in many cases. These special lenses may be a particularly good option for patients who’ve been told their eyes are “difficult to fit” or that they have a condition that prevents them from wearing contact lenses.
Standard contacts can aggravate an extreme case of dry eye, making them almost unbearable to wear. Scleral lenses leave a space between the surface of the cornea and the lens which acts like a tear reservoir, preventing moisture from evaporating and keeping the eye hydrated throughout the day.
Astigmatism is a refractive error caused by an irregular corneal surface. Higher amounts of astigmatism are harder to correct with glasses or soft contact lenses and may not provide optimal vision. Scleral lenses are great for astigmatism because they’re more stable than regular contacts.
Keratoconus is a condition in which the cornea thins and bulges outwards in the center. Because scleral lenses vault over the cornea rather than actually touching it, the reservoir tear film helps to create a uniform regular surface to allow for clearer vision when compared to glasses or soft contact lenses.
How long does a scleral lens fitting take?
Each lens is custom fit for each individual. The process can take several visits in the office. The office visits will include the use of technology like a corneal topographer , Anterior OCT and fluoresceine dyes.

How long can scleral lenses last?
