Medical and Biotech [MESH] Definitions
The making of a continuous circular tear in the anterior capsule during cataract surgery in order to allow expression or phacoemulsification of the nucleus of the lens. (Dorland, 28th ed)
A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision. The small incision allows the surgeon to use very few or even no stitches to close the tiny wound. There is usually no need for hospitalization and patients may resume most activities within days. (Cline, et al., Dictionary of Visual Science, 4th ed & In Focus 1993;1(1):1)
Corneal Endothelial Cell Loss
Loss of CORNEAL ENDOTHELIUM usually following intraocular surgery (e.g., cataract surgery) or due to FUCHS' ENDOTHELIAL DYSTROPHY; ANGLE-CLOSURE GLAUCOMA; IRITIS; or aging.
Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)
Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery. (Dorland, 27th ed; Newell, Ophthalmology: Principles and Concepts, 7th ed, p310-12).
The purpose of this study is to compare the safety and efficacy of manual super small incision cataract surgery (MSSICS) and Phacoemulsification.
To compare the health economic parameter and clinical outcome of Phacoemulsification with small incision cataract surgery (SICS)
Hypothesis : Phacoemulsification is superior to SICS with regards to: - Immediate unaided high and low contrast visual performance - Its impact on quality of life.
