    Techniques of nuclear delivery in Manual small incision cataract surgery

    Manual small incision cataract surgery (MSICS) is now practiced in both developed and developing countries. It involves the extraction of a complete or divided nucleus from the capsular bag through the capsular opening and then through the sclero-corneal tunnel. A number of techniques of nuclear delivery have evolved over the time. These techniques have their own merits and demerits. However they give similar results in the hands of experienced surgeons. The methods are broadly classified as follows: Anterior chamber maintainer technique Microvectis technique Phacofracture technique Phacosandwich technique Fish hook technique Ruit's technique We shall now discuss the difference in steps involved in the various techniques. 1. Anterior Chamber Maintainer technique ( Blumenthal`s technique): Fixing the AC Maintainer (Anterior Chamber Maintainer) After the tunnel has been dissected with a crescent knife, two side ports are made with 19 or 20 G MVR knife, one for capsulotomy and the other f

    Management of Subluxated cataract

    Zonular compromise complicates every step of cataract surgery and poses a serious challenge in terms of safety and visual outcome. When the lens is displaced from its normal position, it is considered subluxated if it remains in the pupillary area and luxated or dislocated if it is completely displaced from the pupil. Ectopia lentis is the term used to describe congenital dislocations.1 Lens displacements may be traumatic, heritable, and spontaneous.( Table 1) Table 1: Causes of Lens Dislocation Causes Features Traumatic Responsible for >50% lens displacements Heritable Associated systemic anomalies Marfans’s syndrome: Triad of skeletal, cardiovascular & ocular anomalies. Autosomal dominant. Generalized thinness and elongation of limbs, sternal deformities, kyphoscoliosis, joint hyperextensibility, low ratio between upper and lower segment, arachnodactyly, cardiopathy, aortic dilatation, dissecting aneurysm, mitral regurgitation. Ectopia lentis: B/L superotemporally, usually partial, r
