Multifocal versus monofocal intraocular lenses after cataract extraction. [PDF]

, 2015
BACKGROUND: Good unaided distance visual acuity is now a realistic expectation following cataract surgery and intraocular lens (IOL) implantation. Near vision, however, still requires additional refractive power, usually in the form of reading glasses ...

Polycarbonate intraocular lenses

Journal of Cataract and Refractive Surgery, 1988
Bisphenol-A polycarbonate has been investigated as an improved polymer for ocular implants, especially for intraocular lenses (IOLs). Polycarbonate properties afford special opportunities for development of tougher, stronger, one-piece IOLs. Autoclave or gamma sterilizability and a higher refractive index may provide additional IOL advantages over ...

Growth factor restriction impedes progression of wound healing following cataract surgery: identification of VEGF as a putative therapeutic target [PDF]

, 2016
Secondary visual loss occurs in millions of patients due to a wound-healing response, known as posterior capsule opacification (PCO), following cataract surgery. An intraocular lens (IOL) is implanted into residual lens tissue, known as the capsular bag,

Changes in forward light scatter parameters as a function of refractive error in young adults [PDF]

, 2020
Background/aims Some aspects of visual performance worsen with increasing myopia. Whilst the underlying causes are not always clear, reduction in retinal image quality is often attributed to structural changes in the posterior myopic eye.

Phakic intraocular lenses and their special indications

Journal of Ophthalmic & Vision Research, 2016
Phakic intraocular lenses revolutionize refractive surgery and continue to serve as an excellent option for vision correction in patients who are not ideal candidates for laser vision correction.

Cauterization technique for suture erosion in transscleralfixation of intraocular lenses

International Journal of Ophthalmology, 2013
Transscleral suturing is a commonly applied technique to fix intraocular implants in the sulcus. A major problem after transscleral implantation is suture erosion that normally happens in the late post-surgery period and may result in an increased ...

Clinical application of accommodating intraocular lens [PDF]

International Journal of Ophthalmology, 2018
The present review describes recent advances in application of accommodating intraocular lenses (AIOLs). Standard monofocal intraocular lenses (MIOLs) only correct distance vision, while AIOLs are designed to allow both good distance vision and near ...

AGEs in human lens capsule promote the TGFβ2-mediated EMT of lens epithelial cells:Implications for age-associated fibrosis [PDF]

, 2016
Proteins in basement membrane (BM) are long-lived and accumulate chemical modifications during aging; advanced glycation end-product (AGE) formation is one such modification. The human lens capsule is a BM secreted by lens epithelial cells. In this study,
