LASIK Outcomes Following Multifocal and Monofocal Intraocular Lens Implantation

Abstract

Laser in situ keratomileusis refinement after cataract surgery with monofocal IOL implantation provides a more accurate refractive outcome than after multifocal IOL implantation. Predictability of LASIK correction is limited in hyperopic eyes implanted with multifocal IOLs.

Vector analysis of astigmatic changes after cataract surgery with toric intraocular lens implantation

“…Today, cataract patients are more demanding and for this reason, cataract surgery is aimed at providing complete and fast visual rehabilitation with minimal postoperative residual refractive errors. 4 In addition to the improvement in biometric devices and IOL power calculations, 5 different IOL designs have been developed and introduced into clinical practice. Some of the designs attempt to improve the optical quality achieved with a standard monofocal IOL, [6][7][8][9][10][11][12] and others attempt to restore not only distance visual function but also intermediate and near vision.…”

Comparison of a new-generation sectorial addition multifocal intraocular lens and a diffractive apodized multifocal intraocular lens

“…[10][11][12][13] Several methods have been proposed in the literature. [10][11][12][13] In our experience, automated refraction has been very helpful in assessing refraction in patients with the Restor SN6AD1 IOL. BissenMiyajima et al 14 found automated refraction with the Restor SN6AD1 IOL to be repeatable and reliable.…”

Vector analysis of astigmatic changes after cataract surgery with implantation of a new toric multifocal intraocular lens

“…14,24,25 One of these advances is the development of more sophisticated IOL designs that provide acceptable retinal image quality at different distances (near, intermediate, and distance). Toric multifocal IOLs were developed to restore visual function at near and distance by compensating for not only defocus but also for astigmatism in eyes with a significant amount of this defect.…”

“…[11][12][13] Toric IOLs are reported to yield an enhanced visual and refractive effect over that with opposite clear corneal incisions, 5 and new flexible model allow surgeons to use smaller incisions, this providing better control of corneal astigmatism and higher-order aberrations (HOAs). 3,13 However, today's cataract patients are more demanding, and they usually seek total visual rehabilitation 14 and total independence from spectacles, both of which require successful near, intermediate, and distance visual restoration. [14][15][16][17] These requirements were the motivating factor in the development of toric multifocal IOLs.…”

[14][15][16][17] These requirements were the motivating factor in the development of toric multifocal IOLs. These IOLs were designed to simultaneously compensate for corneal astigmatism and the loss of accommodative ability after crystalline lens extraction.…”
