Scleral lens for keratoconus: technology update

Clinical Ophthalmology, 2015
Scleral lenses are large diameter lenses which rest over the sclera, unlike the conventional contact lenses which rest on the cornea. These lenses are fitted to not touch the cornea and there is a space created between the cornea and the lens. These lenses are inserted in the eyes after filling with sterile isotonic fluid.

Scleral-fixated intraocular lens implantation techniques

Acta Medica Alanya, 2019
The ideal location of intraocular lens implantation is the posterior chamber. The capsular bag is left during the cataract operations in order to implant the intraocular lens in the position of the crystalline lens and the artificial lens is applied ...

Safe Suture Burial in Trans-scleral Fixation of Posterior Chamber Intraocular Lens

Delhi Journal of Ophthalmology, 2011
The commonest complication of trans-scleral fixation of posterior chamber intraocular lens (PCIOL) is suture erosion. The sutures though crucial for lens stability, if exposed cause discomfort and are a potential source of endophthalmitis.

Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation

Advanced Science, EarlyView.
A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...
