RGP kontakt lenslerin görsel sonuçlarının keratokonus alt gruplarında karşılaştırılması: Kon tipi, kon lokasyonu, hastalığın şiddeti

Amaç: Rose K ve Conflex Air sert gaz geçirgen kontakt lenslerinin görsel performansını keratokonus alt gruplarındaki kon tipi, kon lokasyonu, hastalık şiddetinin değerlendirilmesi amaçlandı. Gereç ve Yöntem: Yetmiş beş hastanın 75 gözü geriye dönük çalışmaya dahil edildi. Her hastaya refraksiyon, düzeltilmemiş görme keskinliğ, gözlükle en iyi düzeltilmiş görme keskinliği, yarıklı-lamba biyomikroskopisifundoskopisi, göz yaşı kırılma zamanı, korneal topografi, kontakt lens ile en iyi düzeltilmiş görme keskinliğini içeren tam bir oftalmolojik muayene yapıldı. Bulgular: Ortalama yaş 25.9±8.3 idi. Otuz altı göze Rose K, 39 göze Conflex Air uygulandı. Rose K grubunda; ortalama logMAR UCVA, BCVA, BCLCVA 0.90±0.33 (aralık 0.30-1.30), 0.55±0.28 (aralık 0.22-1.30), 0.14±0.12 (aralık 0-0.40) idi. Conflex Air grubunda; ortalama logMAR UCVA, BCVA, BCLCVA 0.89±0.38 (aralık 0.301.30), 0.47±0.24 (aralık 0-1.30), 0.08±0.09 (aralık 0-0.40) idi. Tüm hasta gruplarında görme keskinliğinde kontakt lensler ile anlamlı artış tespit edildi (p

Comparison of visual results of RGP contact lenses in keratoconus subgroups: Cone type, cone location, severity of the disease

Aim: It is aimed to evaluate the visual performance of Rose K and Conflex Air rigid gas-permeable (RGP) contact lenses in keratoconus subgroups according to cone types, cone location, and severity of keratoconus. Materials and Methods: Seventy-five eyes of 75 participants were included in this retrospective study. Each participant received a full ophthalmologic examination involving refraction, uncorrected visual acuity (UCVA), best spectacle corrected visual acuity (BCVA), slit-lamp biomicroscopy-fundoscopy, break-up time (BUT), corneal topography, best contact lens corrected visual acuity (BCLCVA). Results: The mean age was 25.9±8.3 years . Rose K was fitted for 36 eyes and Conflex Air was fitted for 39 eyes. In Rose K group; the mean logMAR UCVA, BCVA, BCLCVA were 0.90±0.33 (range 0.30-1.30), 0.55±0.28 (range 0.22-1.30), 0.14±0.12 (range 0-0.40). In Conflex Air group; the mean logMAR UCVA, BCVA, BCLCVA were 0.89±0.38 (range 0.30-1.30), 0.47±0.24 (range: 0-1.30), 0.08±0.09 (range 0-0.40). There were significant increases in visual acuities with contact lenses in both groups (p<0.05). Conclusion: Both contact lenses may improve visual acuity in patients with all subtypes of keratoconus. Rose K contact lens may be better in globus type of keratoconus then oval type.
