| Abstract |
PURPOSE
To evaluate the clinical results of fitting the miniscleral contact lens (MSD; Happy Vision Corp., Anyang, Korea) in patients with corneal abnormalities. METHODS: Thirty-eight patients (56 eyes) fitted with MSD lenses were recruited for this study. Clinical indication, visual acuity, degree of comfort, mean wearing time, parameters of the finally prescribed lenses, number of fittings with trial lenses, success rate with the first prescribed lens, and adverse events were evaluated. RESULTS: Forty-two (75%) of 56 eyes were enrolled in this study due to keratoconus. Other conditions included Stevens-Johnson syndrome (6 eyes, 11%), high postkeratoplasty astigmatism (3 eyes, 5%), corneal scarring (3 eyes, 5%), and ectasia after laser in situ keratomileusis (LASIK; 2 eyes, 4%). The mean log MAR visual acuity improved from 1.01 ± 0.64 to 0.13 ± 0.19 after wearing lenses (p= 0.0001). In 53 eyes (94.6%), patients reported the miniscleral contact lenses to be comfortable, and the mean daily wear time was 12.9 ± 2.5 hours. The mean sagittal depth of finally prescribed lenses was 4.67 ± 0.37 mm (3.7-5.4). An average of 3.3 ± 1.5 (1-7) trials were needed for the trial fitting, and the average number of re-prescriptions to achieve the optimal fitting was 1.5 ± 0.48 (1-3). One patient discontinued the lenses after 3 months due to discomfort. CONCLUSIONS: Miniscleral contact lenses are a good alternative for patients with corneal abnormalities and result in both successful visual outcome and comfort. |
