Specialty Contact Lenses
If you've been diagnosed with corneal irregularities and told you can't wear contacts, your Advanced Eyecare optometrist wants you to know about scleral specialty contact lenses created specifically to correct vision issues caused by corneal irregularities such as keratoconus, corneal dystrophy, pellucid marginal corneal degeneration or ocular trauma.
Specialty contacts like scleral lenses have larger diameters than regular contact lenses and are gas permeable lenses which allow oxygen to diffuse underneath the lenses for better eye health and clearer vision correction. In addition, the space between the anterior surface of hard to fit lenses and your cornea functions as a fluid reserve to improve comfort for those with chronic dry eye syndrome or chronic inflammation.
If you are diagnosed with keratoconus and want to wear contacts, your eye doctor in Manhattan Beach and Redondo Beach may recommend being fitted for scleral contact lenses. Keratoconus causes your cornea to thin and slowly bulge outward until it develops a cone-like shape. This abnormal shape also makes your vision blurry and increases your sensitivity to light. Generally affecting both eyes, keratoconus may be diagnosed in children as young as 10 years old but does not typically affect people older than 25.
Scleral specialty contact lenses are customized to fit the exact curvature perimeters of each eye. Designed to span or vault the surface of a cornea affected by keratoconus, scleral lenses lay on less sensitive areas of the sclera so they feel natural and comfortable. Additionally, hard to fit contacts move minimally when you blink so they remain more stable and secure on your eyes.
People who have had a cornea transplant may benefit from specialty contacts providing significant visual acuity improvements and prevention of infection. Advanced technology in contact lens development and design is also supporting creation of bifocal scleral specialty contacts for correcting age-related presbyopia.
Depending on the condition and/or shape of your cornea following a corneal transplant or keratoconus diagnosis, your optometrist will customize your specialty contacts by determining the appropriate size of your lenses: full scleral (largest diameter), mini-scleral, semi-scleral or corneo-scleral (smallest diameter).
