Abstract

Aim: To evaluate the safety and efficacy of orthokeratology in adults with low to moderate myopia. Material and Method: Twenty- eight eyes of 14 adults (older than 18 years), with manifest refraction sphere less than -5.00 D, cylinder up to 1.0 D, and best spectacle-corrected distance visual acuity of 10/10 were prospectively recruited for this study. Each subject eye was evaluated in regards to the uncorrected and best corrected visual acuities, manifest refraction, slit lamp biomicroscopy, corneal topography and pachymetry before and after contact lens fit. Subject eyes were followed at day-1, week-1, month-1, month-3, month-6, year-1 and year-2 following contact lens fit. Results: The mean follow-up after contact lens fit was 16.7±4.4 months. The mean uncorrected visual acuity was 0.92±0.04 logMAR (~1/10) before contact lens fit, and 0.0±0.0 logMAR (10/10) at the last follow-up examination. The mean best spectacle-corrected visual acuity was 0.0 logMAR (10/10) before contact lens fit and was maintained at all follow-up examinations. The mean manifest refraction spherical equivalent decreased from -2.70±0.14 D pre-contact lens fit, to -0.50±0.08 D at week-1 examination and remained stable thereafter. The mean astigmatic change was 0.50±0.20 D, and no subject eye had induced astigmatism of more than 1.0 D. No contact lens related complication requiring cessation of contact lens wear was encountered. Conclusion: Orthokeratology seems to be safe and effective in the correction of low to moderate myopia in adults.

Özet

Amaç: Erişkinlerde düşük-orta dereceli miyopinin düzeltilmesinde ortokeratolojinin etkinlik ve güvenilirliğinin değerlendirilmesi. Gereç ve Yöntem: Bu prospektif çalışmaya, 18 yaşından büyük, -5,0 D ve altında sferik, 1,0 D ve altında silindirik refraksiyon kusuru olup, düzeltilmiş görme keskinliği 10/10 olan 14 olgunun 28 gözü dahil edildi. Tüm olgu gözlerine görme keskinliği, refraksiyon, biyomikroskopi, pakimetri ve kornea topografisini içeren tam bir oftalmolojik muayene sonrasında ortokeratoloji lensleri uygulandı. Olgular, uygulama sonrası 1. gün, 1. hafta, 1. ay, 3. ay, 6. ay ve 1. yıl da düzeltilmemiş ve düzeltilmiş görme keskinliği, manifest refraksiyon, biyomikroskopi bulguları, kornea topografisi ve kornea kalınlığı açısından değerlendirildi. Bulgular: Ortalama takip süresi 16,7±4,4 aydı. Ortokeratoloji öncesi ortalama düzeltilmemiş görme keskinliği 0,92±0,04 log MAR (~1/10) iken, 1. yılda 0,0±0,0 logMAR (10/10) idi. En iyi gözlükle düzeltilmiş görme keskinliği ortokeratoloji öncesi 0,0 logMAR (10/10) idi ve takip boyunca aynı kaldı. Ortokeratoloji öncesi ortalama manifest refraksiyon sferik eşdeğer -2,70± 0,14 D iken, 1. haftada -0,50±0,10 D’ye düştü ve takip boyunca stabil kaldı. Astig ma tiz ma daki ortalama değişim 0,50±0,20 D idi ve hiçbir gözde 1,00 D’den yüksek indüklenmiş astigmatizma görülmedi. Lensi bırakmaya neden olabilecek herhangi bir komplikasyon izlenmedi. Sonuç: Erişkinlerde düşük-orta dereceli miyopinin düzeltilmesinde, ortokeratoloji güvenilir ve etkili bir yöntem olarak görünmektedir.
