Advantages and Disadvantages

Advantages:

  • Even the most irregular cornea can be fitted with scleral lenses as they are designed to rest solely on the sclera and are fitted to bridge the cornea.
  • They are large in diameter and therefore fit under the eyelids making it almost impossible for them to become dislodged during wear. Similarly they do not move around during wear often resulting in an improvement in comfort and stabilizing the vision compared to some other lens types.
  • They are dimensionally stable, robust and, in general, do not deteriorate rapidly.
  • Insertion and removal can be easier for those who find handling smaller types of lenses difficult due to dexterity problems or poor vision.
  • Powers in excess of ± 40.00 D are possible.

Disadvantages of scleral lenses:

  • The large diameter and lens thickness:
  • Can result in a lower oxygen transmission to the cornea than some other lens types.
  • Can be can be intimidating
  • Can give a feeling of bulk during wear
  • Can cause the lens wearing eye(s) to appear slightly larger than when the lens is not being worn.
  • Are labour intensive, and therefore more costly, to produce compared to most other lens types.
