Use of mini scleral contact lenses in moderate to severe dry eye.
OBJECTIVE
To evaluate fitting feasibility and efficacy of mini scleral contact lenses in moderate to severe dry eye patients.


METHODS
Prospective interventional case series, this study included those patients with grades III and IV dry eye disease, whose symptoms could not be controlled by conventional treatments. Demographic data, UCVA, BSCVA were evaluated before fitting. Mini scleral lens fit was assessed by single experienced practitioner and best corrected vision with mini scleral lens was assessed. After dispensing mini scleral lens, BCVA with mini scleral lens, and possible contact lens related problems were assessed in each visit. Ocular comforts, frequency of artificial tear use, contact lens handling problems were asked in each follow up visit. For those who did not choose to wear lenses, the reason was asked. All data were analyzed using descriptive statistical tests.


RESULTS
Twenty eyes of 13 patients were fitted. Mini scleral lens was dispensed for 19 eyes in them assessment of fit was either ideal (n=9) or acceptable (n=10). Seven patients got their lenses; four patients (seven eyes) of them were satisfied with their lenses based on decrease in discomfort and dry eye symptoms, decrease artificial tear need frequency and improvement in visual acuity during mean follow up period of 18.25 months (range: 15-20). None of them was affected with any contact lens related complication.


CONCLUSIONS
Mini scleral contact lenses can be considered helpful in management of moderate to severe dry eye.
