Abstract

Presbyopia is the physiological degradation of accommodation and still remains as a problem which reduces the quality of life and its surgical management by surgeries including refractive surgery is challenging. Refractive lens change is a treatment modality for presby- opia treatment. With the advances in surgical technics and the increase in population who have presbyopia, the use of intraocular lenses (IOL) became crucial. Many different lenses including multifocal IOLs are implanted to treat presbyopia. None of the IOLs were found to be ideal. Currently accommodative intraocular lenses (AIOL) are under renewal. These lenses use the performance of ciliary body. Two main design concepts exist. First axial shift concept relies on anterior movement of one or two optics creating accommodation abil- ity. Second, relies on the change of IOL curvature or shape. Although the experiences with the fi rst AIOL Crystalens were disappointing, the reported results with the new AIOLs are better. Sulcus is the place preferred for AIOL implantation instead of capsular bag in new design AIOLs. In newer design AIOLs toric ability may be involved.

Özet

Presbiyopi akomodasyonun kaybı olup, henüz refraktif cerrahi dahil cerrahi yaklaşımların tam olarak çözüme ulaştıramadığı kişinin günlük yaşam kalitesini bozan fi zyolojik bir görme problemidir. Presbiyopi tedavisinde refraktif lens değişimi bir tedavi seçeneğidir. Cerrahi tekniklerinin gelişmesi ve presbiyop sayısının gün geçtikçe artması nedeniyle göz içi mercekleri (GİL) ile presbiyopi tedavisi önem kazanmıştır. Şimdiye kadar multifokal GİL dahil olmak üzere birçok denenmiş ancak hiçbiri ideal hedefe ulaşamamıştır. Son yıllarda akomodatif göz içi lensler (AGİL) üzerinde çalışmalar yoğunlaşmıştır. AGİL’ler silyer kasın halen devam eden kasılma fonksi- yonundan yararlanırlar. Bu lenslerde iki temel tasarım kullanılmaktadır. İlki bir veya iki optiğin öne aksiyel hareketi ile akomodasyon sağlamaktır. İkincisi ise kurvatür ve şekil değiştiren tasarımlardır. İlk kullanılan AGİL olan Crystalens hayal kırıklığı yaratsa da yeni geliştirilen GİL’lerle başarılı sonuçlar bildirilmektedir. Yeni tasarım lenslerde AGİL kapsüler kese yerine sulkusa yerleştirilmektedir. Gelecekte bu lenslere torik mekanizmanın da ilave edilebileceği düşünülmektedir.
