  • Title: Intercapsular versus extracapsular cataract extraction.
    Author: Naylor G, Sutton GA, Morrell AJ, Pearce JL.
    Journal: Ophthalmic Surg; 1989 Nov; 20(11):766-8. PubMed ID: 2616122.
    Abstract:
    Forty-five eyes that have undergone routine extracapsular cataract extraction with insertion of a posterior chamber intraocular lens were compared with a similar group of eyes that had undergone intercapsular extraction. Capsular fixation was more predictable following intercapsular (78%) than it was following extracapsular extraction (22%). Gonioscopy revealed prominence of the lens haptic in 22% of the intercapsular group, with peripheral anterior synechiae (PAS) in 18%; haptics were prominent in 78% of the extracapsular group, with synechiae in 55%. Lens eccentricity of 2 mm or more was seen in 2 patients (4%) following intercapsular and in 10 (22%) following extracapsular extraction. Pupil irregularities were noted in three of the intercapsular group (7%) and in eight of the extracapsular group, (13%) with peripheral iris tucking alone in three. These data strongly support the view that intercapsular is superior to extracapsular cataract surgery in terms of facilitating capsular fixation of posterior chamber intraocular lenses.
