Keratoconus is a progressive eye disorder in which the cornea, normally round and dome-shaped, thins and begins to bulge into a cone-like shape. This causes distorted vision and increased sensitivity to light. Usually starting in adolescence or early adulthood, keratoconus can significantly impair vision if left untreated. Dr. Mark Deist, an ophthalmologist in Sandton, Johannesburg, uses the most modern and scientifically validated treatment options to manage this condition,

Cataract surgery has entered a new era — one where technology, precision, and personalization  come together to deliver vision that’s clearer, sharper, and more reliable than ever before. Today, cataract surgery is not just about removing a cloudy lens. It’s about restoring and enhancing vision  — often to levels better than before the cataract developed. And for patients choosing premium intraocular lenses (IOLs) , precision and predictability are everything. That’s where t

Cataract surgery and refractive lens exchange (RLE) have been transformative in restoring clear vision, but for many patients, the goal goes beyond simply seeing better—it’s about regaining freedom from glasses and achieving a natural, seamless visual experience across all distances. The Rayner Galaxy intraocular lens (IOL)  is a groundbreaking advancement in this pursuit. Combining cutting-edge technology with patient-centered design, the Galaxy IOL offers a revolutionary so

The TECNIS PureSee™ IOL is a next-generation , presbyopia-correcting intraocular lens from Johnson & Johnson that’s designed to give patients high-quality distance vision with an extended range into intermediate and functional near vision. It uses a purely refractive, extended depth-of-focus (EDoF)  optical design intended to improve spectacle independence while minimizing common visual disturbances (e.g., halos and glare) associated with older multifocal designs.
