To compare the accuracy of Optiwave Refractive Analysis (ORA) intraoperative aberrometry (Alcon Laboratories, Inc., Fort Worth, TX) with preoperative biometry in predicting residual refractive error a...
To establish the agreement of routine measurements taken before cataract surgery between the Aladdin biometer, which is based on optical low-coherence interferometry (OLCI), and the Lenstar biometer, ...
To analyze biometric parameters and patterns of corneal astigmatism in cataract surgery patients using optical low-coherence interferometry in Northern United Arab Emirates (UAE).
Cataract is a common ailment of the old age hindering daily activities leading to poor quality of life due to poor vision. It is the commonest cause of treatable blindness. In practice, extracapsular ...
Astigmatism correction in cataract surgery is a common surgical challenge. Although there are numerous approaches to its treatment during cataract surgery, there remains a lack of consensus on what le...
Prior to cataract surgery the lens must be calculated to appropriately fit a patient for the intraocular lens implant. Lenstar is an optical biometer that calculates the axial length, kera...
Congenital cataract is the main cause of form deprivation amblyopia in children. Current studies confirm that form deprivation amblyopia affects the retinal nerve fiber layer. However, the...
Cystoid macular edema (CME) can limit visual acuity after cataract surgery. Little is known whether the incidence is similar between standard ultrasound phacoemulsification cataract surger...
Senile cataract is managed by cataract extraction and intra-ocular lens (IOL) implantation. The purpose of this study is to evaluate the safety and efficacy of the SeeLens AF, an acrylic h...

Loss of CORNEAL ENDOTHELIUM usually following intraocular surgery (e.g., cataract surgery) or due to FUCHS' ENDOTHELIAL DYSTROPHY; ANGLE-CLOSURE GLAUCOMA; IRITIS; or aging.
The interdisciplinary science that studies evolutionary biology, including the origin and evolution of the major elements required for life, their processing in the interstellar medium and in protostellar systems. This field also includes the study of chemical evolution and the subsequent interactions between evolving biota and planetary evolution as well as the field of biology that deals with the study of extraterrestrial life.
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)
Evolution at the molecular level of DNA sequences and proteins. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
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)
Ophthalmology is the branch of medicine that is devoted to the study and treatment of eye diseases. As well as mild visual defects correctable by lenses, ophthalmology is concerned with glaucoma, uveitis and other serious conditions affecting the eye, ...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
