Scleral Lenses Can Be Beneficial for Dry Eye Patients in Several Ways

Scleral lenses can be beneficial for dry eye patients in several ways:

1.   Moisture Retention: Scleral lenses are large, gas-permeable lenses that vault over the cornea and rest on the sclera (the white part of the eye). By creating a reservoir of tears between the lens and the cornea, they help to keep the ocular surface continuously lubricated, reducing discomfort associated with dry eyes.
2.  Protection: The design of scleral lenses shields the cornea from the environment, protecting it from irritants such as dust, pollutants, and air currents, which can exacerbate dry eye symptoms.
3.  Stability: Scleral lenses are more stable on the eye compared to smaller corneal lenses. This stability reduces friction and rubbing, which can further irritate dry eyes.
4.  Longer Wear Time: Scleral lenses can typically be worn for longer periods compared to traditional soft contact lenses because they don't directly touch the cornea, reducing the risk of corneal irritation and discomfort associated with dry eyes.
5.  Customization: Scleral lenses are highly customizable to fit the unique curvature and size of each patient's eye. This customization ensures a comfortable fit and optimal vision correction, which can be particularly beneficial for patients with severe dry eye symptoms.
 

Overall, by providing continuous hydration, protection, stability, and vision correction, scleral lenses offer significant relief for dry eye patients.  However, it's essential for patients to consult with an eye care professional to determine if scleral lenses are suitable for their specific condition and needs.
