When is the Boston Scleral Lens Device indicated?
This device should be considered when there are signs of corneal erosions or a history of ulcer despite the aggressive use of lubricants. Whenever possible, this treatment should be initiated early before scarring has occurred or to prevent it from becoming worse since this complication is permanent. The development of a large erosion is more ominous since it is far more difficult for it to heal, generally leaves a denser scar and may require continuous wear of the device that increases the risk of infection. Therefore, when it is indicated, fitting the BSL should be done early. In general, the BSL is an effective alternative to tarsorrhaphy and offers the advantage of not compromising vision, being more cosmetically acceptable and enabling the ophthalmologist to monitor the corneal status more effectively. There are many anesthetic corneas that do not suffer from complications and therefore do not require the BSL. However, infants and young children are an exception to this rule since
