| Popis: |
The lens is transparent, unique, delicate, and highly functional, containing highly organized cells that alter shape by the contraction and relaxation of the ciliary muscle to assist focus on objects at varying distances. The integrity of the corneal posterior is indispensable for the formation of a clear image. Cataract compromises sight and primes degradation of optical clarity due to clouding and lens opacification. Change in structure and organization of characterized lens fibers increases light scattering dramatically, reducing lens performance. The primary objective of cataract surgery is translated by restoring vision and substantially regaining interaction with the surroundings to improve patients' quality of life with considerable gains in social and emotional life . The ideal goal for achieving full refractive correction relies on implantation of intraocular lenses (IOLs) to replace the eye's native lens. The evolution of these IOLs has stimulated pioneers to progress with phacoemulsification devices and operative techniques with increasingly smaller incisions. The technique offers promising outcomes with advanced performance capabilities and tailored rehabilitation for individual lifestyle needs such as reading and driving. Previous expectations of cataract surgery-induced improvements no longer consider the need for thick spectacle lenses rather to optimize modern psychometric methods. |
