Corneal inlay

Corneal inlay is a surgical procedure aimed at improving near vision in people who have lost this ability due to presbyopia or other refractive errors. The procedure involves the insertion of a small, thin device into the cornea, which is the clear, front part of the eye. This device is designed to change the shape of the cornea, thereby improving the eye's ability to focus on close objects.

Procedure

The corneal inlay procedure is typically performed on an outpatient basis using topical anesthesia. A laser is used to create a small pocket or flap in the cornea, into which the inlay is inserted. The specific design and material of the inlay can vary, but they are generally made to be biocompatible and minimally noticeable once in place. After the inlay is positioned, the corneal flap or pocket is closed, and the healing process begins.

Types of Corneal Inlays

There are several types of corneal inlays, each designed with different features to address specific visual needs. Some of the most common include:

• Kamra inlay: Designed to increase depth of focus by creating a small-aperture effect.
• Raindrop Near Vision Inlay: Works by reshaping the anterior curvature of the cornea to improve near vision.
• Flexivue Microlens: A refractive inlay that provides a bifocal-like effect, with different zones for near and distance vision.

Candidates

Ideal candidates for corneal inlay surgery are typically those who have difficulty with near vision due to presbyopia and who wish to reduce their dependence on reading glasses. However, not everyone is a suitable candidate. Factors such as corneal thickness, eye health, and the presence of other eye conditions can affect eligibility for the procedure.

Risks and Complications

As with any surgical procedure, there are risks associated with corneal inlays. These may include infection, inflammation, changes in vision, and the need for additional surgery. In some cases, the inlay may need to be removed if complications arise or if the desired visual outcome is not achieved.

Recovery and Results

Recovery times can vary, but many patients report improvements in their near vision shortly after the procedure. It is important for patients to follow their eye doctor's post-operative care instructions to ensure the best possible outcome. Regular follow-up visits are necessary to monitor the healing process and to assess the effectiveness of the inlay.

Conclusion

Corneal inlay surgery represents a significant advancement in the treatment of presbyopia and other refractive errors affecting near vision. By offering a minimally invasive option for vision correction, this procedure can greatly enhance the quality of life for many individuals. However, it is important for potential candidates to thoroughly discuss the risks, benefits, and alternatives with their eye care professional to make an informed decision.
