Optical rehabilitation of a patient after keratitis using a fenestrated scleral lens: a case report

Relevance . The use of scleral contact lenses (SCLs) is currently indicated for patients with complex ametropia and irregular corneal surfaces resulting from various causes. SCLs are effective in cases of intolerance to other vision correction methods or when glasses or standard contact lenses fail to provide satisfactory visual function and optical rehabilitation. A critical factor in SCL design is ensuring sufficient oxygen transmission for safe wear, which can be enhanced by fenestration. The study aims to demonstrate the possibility of optical rehabilitation in a post-keratitis patient using fenestrated scleral lenses made of Optimum Infinite material. Objective : to demonstrate the possibility of optical rehabilitation in a post-keratitis patient using fenestrated scleral lenses made of Optimum Infinite material. Materials and methods. A patient born in 2013 presented with complaints of low visual acuity. The patient’s history included keratitis, leading to ametropia uncorrectable with glasses. In addition to standard examinations, corneal topography, pachymetry, and morphological evaluation via scanning confocal microscopy were performed. Results . A scleral contact lens (OKVision SMARTFIT®) made of high-oxygen-permeable Contamac Optimum Infinite material with fenestration (1 × 0.3 mm) was fitted. The patient’s visual acuity improved from 0.08 to 0.9 after lens fitting. No complications associated with lens wear were observed during the follow-up period. Conclusions . Scleral contact lenses made from the high-oxygen-permeable material Contamac Optimum Infinite with fenestration can be recommended for optical correction in patients with ametropia induced by keratitis.
