Abstract

Purpose: To evaluate the long-term results of rigid gas permeable (RGP) contact lenses in severe keratoconic eyes. Material and Method: Severe keratoconic eyes with RGP contact lenses were evaluated retrospectively.Results: Long-term follow-up results of RGP contact lenses applied to 59 eyes of 42 patients (25 women, 17 men) with a diagnosis of severe keratoconus were analyzed. Follow-up period was 3 to 12 years (mean: 6.57±3.60). The mean age at first exam was 25.88±9.10 years, the mean corneal curve K1 was 6.49±0.40 mm and K2 was 5.91±0.40 mm. Mean visual acuities with spectacles and contact lenses were 0.26±0.10 lines (0.63±0.20 logMAR) and 0.66±0.20 lines (0.20±0.10 logMAR), respectively. The difference between both visual acuities was statistically significant (p=0.0001). At the last visit, the mean visual acuity with RGP contact lenses was 0.68±0.20 lines (0.19±0.10 logMAR). There was no statistically significant difference in visual acuity between first and last examinations with contact lenses (p=0.32). During the long-term follow-up period, apical scarring developed in 17 eyes. Only the 2 eyes of one patient needed penetrating keratoplasty after 6 years of RGP contact lens use. Discussion: Use of RGP contact lenses should be considered before penetrating keratoplasty in cases of severe keratoconus. (Turk J Ophthalmol 2012; 42: 202-6)

Özet

Amaç: İleri keratokonuslu gözlerde sert gaz geçirgen(SGG) kontakt lens kullanımının uzun süreli takip sonuçlarını değerlendirmek. Gereç ve Yöntem: SGG kontakt lens uygulanan ileri keratokonuslu gözler retrospektif olarak incelendi.Sonuçlar: İleri keratokonus tanısı konup gaz geçirgen kontakt lens uygulanan 25 kadın 17 erkek 42 hastanın 59 gözü çalışma kapsamına alındı. Hastalar 3 ile 12 yıl (ortalama 6,57±3,60) takip edildi. İlk muayenede yaş ortalaması 25,88±9,10; K1 değeri ortalaması 6,49±0,40 mm, K2 değeri ortalaması 5,91±0,40 mm. idi. Gözlük ve kontakt lens ile ortalama görme keskinlikleri 0,26±0,10 (0,63±0,20 logMAR) ve 0,66±0,20 (0,20±0.10 logMAR) bulundu. Görme keskinlikleri arasındaki fark istatistiksel olarak anlamlıydı(p=0,0001). Son muayenede SGG kontakt lens ile ortalama görme keskinliği 0,68±0,20 (0,19±0,10 logMAR) idi. İlk ve son muayenelerde kontakt lens ile alınan görme keskinlikleri arasında istatistiksel olarak anlamlı bir fark yoktu (p=0,32). Uzun takip süresi sonunda 17 gözde apikal skar gelişti. Sadece bir hastanın 2 gözüne 6 yıl SGG kontakt lens kullanımından sonra keratoplasti gerekti.Tartışma: İleri keratokonusu olan gözlerde SGG kontakt lensler, keratoplasti öncesi mutlaka düşünülmelidir.
