Purpose
To assess the effectiveness of mini-scleral contact lens and its impact on clinical evaluations for ocular surface diseases.
Setting
This study was conducted in 2024 in Tehran, Iran.
Methods
A total of 54 eyes from 31 patients diagnosed with ocular surface diseases underwent evaluation for mini-scleral contact lens treatment. Assessments included best-corrected visual acuity (BCVA), the Schirmer test, tear film breakup time (TBUT), corneal staining, and Ocular Surface Disease Index (OSDI) questionnaires before and after lens use.
Results
Mini-scleral contact lenses were fitted to 54 eyes from 31 patients for the management of ocular surface diseases. The underlying conditions included Sjögren’s syndrome (19 eyes), Stevens-Johnson syndrome (28 eyes), post-refractive surgery dry eye (2 eyes), and undifferentiated ocular surface disease (5 eyes). BCVA improved significantly from 0.80 ± 0.59 logMAR with habitual correction to 0.31 ± 0.41 logMAR with mini-scleral lenses (P < .001). Schirmer test values increased from 3.8 ± 3.91 to 5.1 ± 4.12 mm/5 min (P<.001), TBUT improved from 2.83 ± 1.92 to 3.39 ± 2.34 seconds (P<.001) after six months of lens use. Additionally, significant improvements in dry eye symptoms and quality of life were observed based on OSDI questionnaire results.
Conclusions
Mini-scleral contact lenses enhance BCVA, improve dry eye parameters, and alleviate symptoms in patients with ocular surface disease.
