Özet

PURPOSE:

To discuss the conditions in which we chose to fit scleral contact lenses and our success in terms of patient compliance.

 

MATERIALS AND METHOD

This study is a single-center, retrospective cross sectional study, including patients who underwent scleral lens fitting between 2018 and 2023, mainly to improve vision. All patients underwent Pentacam corneal topography examination before a full ophthalmological examination. Uncorrected, spectacle-corrected and scleral lens corrected visual acuity were evaluated with Snellen and converted to Log Mar. Success was defined as scleral lens use for more than 1 year.

 

RESULTS

31 patients (46 eyes) were enrolled, of whom 19 (%61,3) were male. The mean age was 37,41±14,81 years (range: 12-71 years). Twenty two eyes with keratoconus, 10 eyes with refractive error after penetrating keratoplasty, 8 eyes with irregular astigmatism due to corneal scar, 4 eyes with advanced stage Steven-Johnson syndrome and 2 eyes with severe dry eyes were included. The appropriate lens was determined after 3,65±1,92 trials (range: 1-8 trials. Five patients did not want to purchase the lens after the application; The lens was successfully worn by 35 eyes of 26 patients. Mean follow-up was 50,61± 50,11 months (range:1-180) Mean uncorrected visual acuity 1,089, mean spectacle-corrected VA was 0,668, mean BCVA with scleral lens was 0,126 and the difference was statistically significant (p˂0.0001). BCVA remained stable and no serious complications were noted during follow-up.

 

CONCLUSION:

Scleral lens fit is a time-consuming practice for the ophthalmologist and an intimidating task for the patient, However their comfort and stability is superior to both rigid gas-permeable or hybrid lenses besides good optical results. Although the large diameter may seem like the major disadvantage during trial, the cost becomes more of an issue in developing countries.
