Keratoconus, scleral lenses and glaucoma drainage implant

Purpose:

This case report describes scleral lens fitting for advanced keratoconus in combination with additional glaucoma surgery.

Material and Methods:

The implantation of a drainage implant was followed by the bilateral fitting of scleral lenses. For contact lens fitting, it was essential to work with a scleral lens system that allows individual zone size and edge clearance in the scleral alignment zone to prevent provocation of the postoperative area.

Results:

Due to the individualized design of the scleral lenses, the patient was able to wear scleral lenses again postoperatively with successful implantation of a drainage implant. A 
prerequisite for this was also that the surgeon considered the necessity of a later postoperative fitting with scleral lenses when choosing the surgical method. 

Conclusion: 

Scleral lenses can also be successfully fitted in cases of complex corneal shapes and surgical procedures on the eye. This requires not only a great clinical experience in fitting such contact lenses, but also an individual manufacturing of the contact lenses based on the contact lens parameters specified by the contact lens specialist.
