How do scleral contact lenses correct distorted vision?

Scleral contact lenses correct distorted vision by creating a smooth, regular surface over the cornea, which is the clear front surface of the eye. Distorted vision can occur when the cornea is irregularly shaped, resulting in astigmatism, keratoconus, or other corneal irregularities.

Scleral lenses vault over the cornea and rest on the sclera, the white part of the eye, creating a tear-filled chamber between the lens and the cornea. This chamber filled with saline solution helps to maintain a constant and smooth optical surface for light to pass through to the retina, which is located at the back of the eye. The tear-filled chamber also provides a cushioning effect, protecting the cornea and providing relief for dry eyes.

By creating a smooth and regular surface over the cornea, scleral lenses can correct vision distortions caused by corneal irregularities, resulting in improved visual acuity, better contrast sensitivity, and reduced glare. Additionally, because scleral lenses are custom-fit for each individual eye, they can provide a more precise correction of vision compared to traditional contact lenses or eyeglasses.

How long will it take to get used to scleral lenses?

The time it takes to get used to scleral lenses can vary from person to person. Some people may adapt quickly within a few days, while others may take several weeks or even months to get used to the lenses.

The adjustment period may depend on various factors such as the individual's eye shape and size, the type of scleral lens being used, the reason for wearing the lens, and the individual's comfort level with inserting and removing the lenses.

It's essential to follow the instructions provided by your eye care professional regarding the insertion, removal, and care of the lenses. It's also recommended to wear the lenses for gradually increasing periods each day to help your eyes adjust to the lenses.

If you are experiencing discomfort or difficulty with your scleral lenses, it's important to speak with your eye care professional. They can offer guidance and make any necessary adjustments to help you achieve the best possible vision and comfort with your lenses.

Conclusion:

Scleral contact lenses can correct distorted vision by creating a smooth, regular surface over the cornea, which helps to improve visual acuity, and contrast sensitivity, and reduce glare. The tear-filled chamber between the lens and the cornea also provides a cushioning effect and can offer relief for dry eyes. Scleral lenses are custom-fit for each individual eye, providing a more precise correction of vision compared to traditional contact lenses or eyeglasses. However, the time it takes to get used to scleral lenses can vary from person to person, and it's important to follow the instructions provided by your eye care professional to achieve the best possible vision and comfort with your lenses.
