What is Corneal Ectasia?
Corneal Ectasia is an eye disorder with distortion in the cornea or due to a peripheral bulge of the corneal layer. One of the factors for the disease could be undergoing the LASIK for eyesight problems. Post LASIK might result in dry eyes, which is the primary symptom of Ectasia.
Scleral Contact Lenses
Scleral lenses have been thoroughly researched and have been found to maintain the right level of moistness in the eyes, thus preventing the Ectasia to develop. Keratoconus is one form of Ectasia which can be corrected with the regular use of scleral lenses. Scleral lenses are generally twice the size of standard lenses.
Scleral lenses are also advised for additional protection soon after the LASIK surgery. Scleral lenses provide more comfort than the standard lenses. Thus, the strain for a patient post LASIK is reduced when wearing scleral lenses, and hence, the chances of getting afflicted with Corneal Ectasia is also less.
In the recent times, scleral lenses have been upgraded, and they are wholly permeable and aerated as well. The glasses still prevent foreign substances from attacking the eyes. These lenses make the eyes comfortable for a longer duration than the standard eye lenses. They are gas permeable lenses. Scleral lenses act as a liquid reservoir over the eyes. The size of the lens depends on the complexity of the disorder.
As the complexity of the disorder decreases with time, the lens size can also be changed. Other than Corneal Ectasia, scleral lenses are also prescribed for Sjogren’s syndrome by doctors. Scleral lenses are usually termed as “Special-effect contact lenses.” So, do not worry when your doctor prescribes scleral lenses.
