Central Corneal Edema with Scleral-Lens Wear

Scleral contact lens wear in unilateral aphakia.

Corneal response to rigid contact lens wear.

Three adult rhesus monkeys were subjected to 2 and 24 hours of polymethylmethacrylate (PMMA) contact lens wear. The induced corneal changes were examined with the electron microscope. Mild epithelial oedema as well as early degenerative cell changes was present already after 2 hours' wear. Rigid lens wear for 24 hours produced more severe oedema and cell alterations together with premature cell...

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...

Infectious keratitis with corneal perforation associated with corneal hydrops and contact lens wear in keratoconus.

BACKGROUND Corneal perforation is an uncommon complication associated with keratoconus. The first cases of infectious keratitis and corneal perforation associated with corneal hydrops and contact lens wear are reported in two keratoconus patients. METHODS A retrospective chart review and histopathological examination were carried out. RESULTS Both patients progressed to corneal perforation ...

Post-lens tear turbidity and visual quality after scleral lens wear.

BACKGROUND The aim was to evaluate the turbidity and thickness of the post-lens tear layer and its effect on visual quality in patients with keratoconus after the beginning of lens wear and before lens removal at the end of eight hours. METHODS Twenty-six patients with keratoconus (aged 36.95 ± 8.95 years) participated voluntarily in the study. The sample was divided into two groups: patients...
