Can Keratoconus Be Cured?

What is keratoconus?

Keratoconus, a progressive eye disorder, affects the shape and structure of the cornea, resulting in distorted and blurry vision. This condition affects approximately 1 in every 2000 individuals, commonly appearing during puberty or late teens, and can continue to progress until around the age of 30. As this disorder can significantly impact the quality of life for those affected, the question arises: can keratoconus be cured?

What causes keratoconus?

Before diving into the potential treatments and management options, it is important to understand the root cause of keratoconus. The cornea, which is normally round and dome-shaped, weakens and begins to bulge forward in individuals with this condition. The exact cause is still not fully understood; however, there are several theories that suggest genetics, abnormal collagen structure, hormonal imbalance, and excessive eye rubbing may contribute to its development. While the precise cause may vary among individuals, the hallmark of keratoconus is the thinning and protrusion of the cornea, leading to visual distortions and irregular astigmatism.

Scleral Lenses

Traditionally, the initial treatment option for keratoconus has been the prescription of specialty contact lenses called scleral lenses. These lenses help to reshape the cornea, compensating for the irregularities caused by keratoconus and improving visual acuity. However, as the disorder progresses, these conventional forms of treatment may become insufficient. In such cases, there are several advanced treatment options available.

Corneal cross-linking

Corneal cross-linking (CXL) has emerged as a promising treatment for keratoconus. CXL involves the application of riboflavin (vitamin B2) eye drops to the cornea, followed by exposure to ultraviolet (UV) light. This process helps to strengthen the collagen fibers within the cornea, stopping or slowing down the progression of keratoconus. As a minimally invasive procedure, CXL offers relatively quick recovery times and has shown favorable long-term outcomes in many patients.


Another option for advancing keratoconus is Intacs, also known as intrastromal corneal ring segments. Intacs are small, transparent, semi-circular plastic devices that are surgically inserted into the cornea. Placed in the periphery of the cornea, these segments help to reshape and stabilize the cornea, reducing irregular astigmatism and improving visual acuity. While Intacs do not cure keratoconus, they can provide significant improvements in vision for many patients.

Corneal Transplant

For individuals who do not find adequate relief from traditional treatments or intra-corneal ring segments, a surgical procedure such as a corneal transplant may be considered. Corneal transplantation involves replacing the diseased cornea with a healthy donor cornea. It is important to note that a corneal transplant is typically reserved for severe cases of keratoconus, as it is a more invasive treatment option with a longer recovery period.

Setting Expectations

Despite the advancements in treatment options, it is essential to manage expectations. While these treatments can help stabilize keratoconus progression and improve visual acuity, they may not necessarily result in a complete cure. The aim of treatment is to halt the progression of the disorder, improve vision, and enhance the patient’s quality of life.

Furthermore, the success of these treatments may vary from person to person, as each case of keratoconus is unique. Factors such as the severity of the condition, age, and general ocular health can influence the outcomes. It is essential for individuals with keratoconus to work closely with an experienced ophthalmologist or cornea specialist to determine the most suitable treatment plan.

Next steps in dealing with keratoconus

In conclusion, while a complete cure for keratoconus may not currently exist, there are several treatment options available that can effectively manage and stabilize the condition. From scleral contact lenses to innovative approaches such as corneal cross-linking and intrastromal corneal ring segments, individuals with keratoconus have access to various options for improving their vision and quality of life. It is important for patients to seek early diagnosis and appropriate treatment to prevent further progression of the disorder. With advancements in technology and ongoing research, the future holds promising possibilities for better management and, potentially, a cure for keratoconus.
