Scleral Contact Lenses Effective in Managing Patients with Pellucid Marginal DegenerationPellucid marginal degeneration is difficult to treat and patients suffering from this condition often have to live with very poor vision. Fortunately, new contact lens designs seem to be more effective in dealing with the problem, which has been confirmed by a team of scientists led by Dr Varsha M. Rathi.

The researchers set out to evaluate how PROSE (prosthetic replacement of the ocular surface ecosystem) scleral contact lenses affect the vision of individuals with pellucid marginal degeneration. The study was carried out in India and included data gathered over a period of three years.

Twelve patients with clinical PMD (some of whom also had keratoconus) were fitted with the tested contact lenses. The reasons for fitting the lenses were varied and included failure of piggy-back systems and rigid gas permeable contact lenses as well as instability of previously used soft contact lenses. After scleral contact lenses were fitted, the patients reported significantly better vision.

The authors of the study concluded that PROSE scleral contact lenses are very effective in managing PMD and can be recommended by eye care practitioners.
