When Is a Corneal Transplant Needed? Many patients with keratoconus can successfully manage their condition with treatments such as corneal cross-linking, specialty contact lenses, CTAK, or other vision-correcting procedures. However, there are situations where these treatments are no longer enough. As keratoconus progresses, the cornea can become severely distorted, significantly affecting vision and quality of […]

Not Everyone Needs a Full Corneal Transplant For patients with keratoconus or other irregular corneal conditions, it can sometimes feel like there are only two options: continue relying on specialty contact lenses or eventually undergo a corneal transplant. The reality is often more nuanced. Many patients fall somewhere in the middle. Their corneas are irregular […]

For decades, patients with advanced keratoconus faced limited treatment options. Glasses and contact lenses could help in the early stages, but once the condition progressed, many patients were left with only one surgical path: a corneal transplant. While corneal transplantation remains a life-changing procedure for many, it is invasive, carries risks, and requires a lengthy […]

This article highlights advancements in wavefront-guided scleral lenses, summarizing the pioneering work of Dr. John Gelles and his team at the Cornea and Laser Eye Institute (CLEI). Their expertise and contributions have helped define the transformative potential of this technology for patients with complex corneal conditions. This summary draws from peer-reviewed publications and abstracts presented […]

Corneal Tissue Addition Keratoplasty (CTAK) is an exciting option in modern keratoconus treatment. Yet myths swirl around any new-sounding procedure, and lingering misconceptions can delay people from getting the sight-saving help they need. Below, we tackle the most common misunderstandings so you can make informed choices about keratoconus management with confidence. Myth 1: “Corneal Tissue […]

Overview Scleral lenses can dramatically improve vision and comfort for people with keratoconus, dry eye, and other corneal conditions—but putting them on and taking them off takes practice. Whether you’re new to lenses or looking for a refresher, here are some of the top tips covered in this guide: Scleral lenses are becoming increasingly being […]

Understanding Keratoconus: A Progressive Eye Condition Keratoconus is a progressive eye disorder that affects the shape of your cornea, the clear front surface of your eye. In this condition, the normally round cornea begins to thin and bulge outward, taking on a cone-like shape. This distortion can lead to significant vision problems, including blurry or […]

Ocular rosacea is a subtype of rosacea, a chronic inflammatory skin disorder that primarily affects the facial area. Ocular rosacea specifically targets the eyes and eyelids, causing a range of symptoms such as redness, dryness, burning, stinging and irritation. Ocular rosacea can be challenging to manage, as it often coexists with other eye conditions and […]

The CLEI Center for Keratoconus is world-renowned for innovating and improving upon corneal surgical techniques. One such technique is corneal tissue addition keratoplasty (CTAK). Unlike treatments that simply focus on addressing refractive errors, CTAK was envisioned as a procedure that could address the underlying structural irregularities associated with keratoconus. In 2016, clinical trials for this […]

What is Corneal Crosslinking? Collagen is a crucial protein found throughout our bodies, providing strength and support to various tissues, including corneal tissue. However, for patients with keratoconus, the collagen fibers in the cornea weaken and become susceptible to deformation. The compromised corneal tissue eventually loses its symmetrical dome shape, bulging outwards and resulting in […]
