Toris k silicone hydrogel contact lens for the optical management of keratoconus

Amaç: Keratokonus hastalarının görsel rehabilitasyo- nunda Toris K silikon hidrojel lensinin etkinliğini değer- lendirmek. Materyal ve Metot: Retrospektif çalışmaya 58 hastanın 100 gözü dahil edildi. Hastaların ortalama yaşı 27,04± 9,5 yaş (aralık: 13-55) idi ve 15 göz grade 1, 28 göz grade 2, 13 göz grade 3, 44 göz grade 4 keratokonus idi. Düzeltilmemiş en iyi görme keskinliği, gözlükle düzeltilmiş en iyi görme keskinliği, korneal topografik ölçümler ve pakimetrik değerler kayıt edildi. Ortalama korneal kırıcılık 50,84±4,36D (aralık:43,40-60,90). Kontakt lens uygulandıktan sonra görme keskinlikleri ve değişim- ler kayıt edildi. Tüm hastalar için izlem süresi 1 yıl idi. Bulgular: Ortalama düzeltilmemiş görme keskinliği (DGK) 0,80±0,40 logMAR (aralık: 0,1-2) idi. Ortalama gözlükle düzeltilmiş en iyi görme keskinliği (GDGK) 0,46±0,26 logMAR (aralık: 0,1-1,3) idi. Ortalama kontakt lensle düzeltilmiş en iyi görme keskinliği (KLDGK) 0,14±0,11 (aralık: 0-0.5) idi. Ortalama görme keskin- likleri gözlüğe kıyasla kontakt lensle daha iyi idi (p

ABSTRACT Background: To determine the efficiency of the Toris K silicone hydrogel contact lens for the optical manage- ment of keratoconus. Material and Methods: 100 eyes of 58 patients were included in this retrospective study. Mean age was 27.04±9.5 year (range: 13-55) and 15 eyes were grade 1, 28 eyes were grade 2, 13 eyes were grade 3, 44 eyes were grade 4 keratoconus. Uncorrected visual acuity, best spectacle corrected visual acuity, corneal topographic measurements and pachymetric values were recorded. Mean corneal power was 50.84±4.36 D (range: 43.40- 60.90). After contact lens fitted we checked visual acuity and recorded the difference. Follow up time was a year for all patients. Results: Mean uncorrected visual acuity (UCVA) was 0.80±0.40 logMAR (range: 0.1-2). Mean best spectacle corrected visual acuity (BSCVA) was 0.46±0.26 logMAR (range: 0.1-1.3). Mean contact lens corrected visual acuity (BCLCVA) was 0.14±0.11 (range: 0-0.5). Mean visual acuities were better with contact lens then spectacles corrections (p<0.01). Mean line gain was 3.83±1.36 (range: 1-7) on Snellen. 83 eyes gained three or more lines on Snellen. We do not have any complications on follow-up time. Conclusions: Toris K silicone hydrogel contact lenses are a promising alternative for the optical management of all grades of keratoconus.
