Cataract – 1

The term coloboma is derived from the Greek termkoloboma, meaning mutilated or curtailed. The malformation refers to a notch, gap, hole or fissure in any of the ocular structures. (1)

Posterior capsule opacification (PCO) is the most common complication followingcataract surgery and  is generally treated with Nd:YAG laser capsulotomy. Several factors play a role in the formation of posterior capsule opacification (PCO) such as variations in surgical technique, patient characteristics, lens design, design of the edge of the lens and lens material used.8-10A complete 360-degree cover of the anterior capsulorhexis over the intraocular lens (IOL) optic also influences PCO development.11-14

Posterior Chamber IOL subluxation or dislocation as a late complication of cataract surgery is uncommon but represents one of the most serious complications & has been reported with increasing frequency in recent years.1-4 The incidence of surgery specifically due to late dislocated IOL is 0.032–0.28%.5-6

Purpose:To assess the repeatability and agreement of a new swept source optical coherence tomography biometer an optical low coherence reflectometer, a dual scheimpflug ray tracing biometer and a Partial Coherence Interferometer AL scan to measure the keratometry (K), Astigmatism (AST), Axial length (AL), Anterior chamber depth (ACD), central corneal thickness (CCT) and white-to-white (WTW) in cataractous eyes in a prospective study.

Several techniques have been defined and compared for chopping nucleus in hard mature cataract, but still many surgeons report difficulty with full thickness division of hard leathery nucleus. We aim to describe a new technique to chop hard mature nucleus, which has enabled a successful full thickness nuclear division through the posterior plate in 100 per cent of the attempted cases, with ease and safety. This technique unfolds a whole new dimension in mechanics of nuclear segmentation.

Cataract is a leading cause of blindness worldwide. Fortunately it is curable.  A patient having   cataract, his/her visual acuity will be up to hand movement or perception of light and projection of rays, but after cataract surgery visual acuity will be 6/6.   From very beginning cataract surgery was not so easy and safe. We had so many bad experiences regarding intra capsular cataract extraction. We have overcome this situation by introducing extra capsular cataract extraction instead of ICCE, to minimize the complications which normally occurred during intra capsular cataract extraction surgery.

Pellucid Marginal Degeneration is a non inflammatory corneal condition typically characterized by bilateral ectasia in inferior & peripheral regions of cornea with regular astigmatism.

Patients with microcornea are usually left aphakic as the routine IOLs with their large size would end up with disastrous complications such as angle closure and glaucoma. The routine size IOLs are therefore not suitable. We planned to use custom made optic and total size small IOLs for these eyes with corneas smaller than 9.0 mm diameter.

Modern cataract surgery has moved ahead from mere implantation of transparent synthetically made Intra Ocular Lenses (IOLs) to techniques that provide greater degree of spectacle independence post surgery. Toric IOLs offer us the opportunity to correct astigmatism and make the patient spectacle independent for distance vision.
