Anatomical and functional outcomes of toric intraocular lens implantation

Journal of Marine Medical Society, 2019
Background: To minimize the residual refractive correction, toric intraocular lens (TIOL) is being increasingly used in cases undergoing cataract surgery with preexisting corneal astigmatism of ≥1.0 D.

Post-keratoplasty astigmatism management by relaxing incisions: a systematic review

Eye and Vision, 2017
Postoperative visual acuity can be limited by post-keratoplasty astigmatism, even with a clear corneal graft. Astigmatism management can be performed by selective suture removal, adjustment of sutures, optical correction, photorefractive procedures ...

Refractive Outcomes after Cataract Surgery

Diagnostics, 2022
A post-operative manifest refractive error as close as possible to target is key when performing cataract surgery with intraocular lens (IOL) implantation, given that residual astigmatism and refractive errors negatively impact patients’ vision and ...

Femtosecond laser-assisted cataract surgery after corneal refractive surgery

Scientific Reports, 2022
Cataract is the leading cause of blindness worldwide, and advanced cataract techniques such as femtosecond laser-assisted cataract surgery (FLACS) have been commercially available. Corneal refractive surgery (CRS) is one of the most popular surgeries for
