Scleral asymmetry as a potential predictor for scleral lens compression

Scleral lens for keratoconus: technology update.

Scleral lenses are large diameter lenses which rest over the sclera, unlike the conventional contact lenses which rest on the cornea. These lenses are fitted to not touch the cornea and there is a space created between the cornea and the lens. These lenses are inserted in the eyes after filling with sterile isotonic fluid. Generally, scleral contact lenses are used for high irregular astigmatis...

Scleral contact lens wear in unilateral aphakia.

For a better understanding of scleral contact lens-related pathophysiology.

Scleral contact lens technology had been applied for several years as part of the treatment of ocular surface diseases, as well as for compensation of corneal surface irregularities. In recent years, new scleral lens designs were developed to compensate for current refractive errors. Becoming more widely used, it is crucial to question the long-term effects of their presence on ocular health. O...

Scleral lens tolerance after corneal cross-linking for keratoconus.

PURPOSE Subjective and objective evaluation of scleral lens tolerance and fitting before and after corneal cross-linking (CXL) for progressive keratoconus. METHODS In this prospective cohort, evaluations were made of 18 unilateral eyes in patients who underwent CXL and had been wearing scleral lenses before the procedure. All the patients gave informed consent; they were able to cooperate wit...

Wavefront-guided scleral lens prosthetic device for keratoconus.

PURPOSE To investigate the feasibility of correcting ocular higher order aberrations (HOAs) in keratoconus (KC) using wavefront-guided optics in a scleral lens prosthetic device (SLPD). METHODS Six advanced KC patients (11 eyes) were fitted with an SLPD with conventional spherical optics. A custom-made Shack-Hartmann wavefront sensor was used to measure aberrations through a dilated pupil wea...
