Scleral Contact Lenses: Pros, Cons, and the Fitting Process

Scleral lenses are a type of contact lens that rest on the sclera, or the white part of the eye, rather than the cornea. They are larger than standard contact lenses, covering the entire cornea and resting on the sclera, which makes them ideal for people with irregular corneas or other eye conditions that make it challenging to wear standard contact lenses. This article will discuss the pros and cons of scleral lenses, vision expectations, and the fitting process.

Pros and Cons of Scleral Lenses

Pros:

1. Comfort: Scleral lenses are designed to be more comfortable than standard contact lenses, as they do not touch the cornea. The space between the lens and the cornea is filled with saline solution, which provides a cushioning effect.

2. Vision: Scleral lenses can provide sharper, clearer image for people with irregular corneas or other eye conditions. They can also provide better depth perception, especially in low-light conditions.

3. Protection: Scleral lenses can protect the cornea from damage, providing a barrier between the eye and the environment.

Cons:

1. Cost: Scleral lenses are typically more expensive than standard contact lenses.

2. Fitting process: The fitting process for scleral lenses is more involved and time-consuming than for standard contact lenses, as each lens is custom-made for the individual.

3. Maintenance: Scleral lenses require special care and maintenance, including cleaning and disinfecting and special solutions.

Vision Expectations

The vision expectations with scleral lenses are generally excellent. People with irregular corneas or other eye conditions that make it challenging to wear standard contact lenses can experience significantly improved visual acuity with scleral lenses. The larger size of the lenses also provides better stability and less movement, which can lead to better visual acuity.

Fitting Process

The fitting process for scleral lenses is more involved and time-consuming than standard contact lenses. It typically involves multiple visits to the eye doctor, as each lens is custom-made for the individual. During the fitting process, the eye doctor will measure the eye's shape and size and consider any specific needs of the individual. Once the lenses are ordered, the individual will return for a final fitting, where the doctor will ensure that the lenses are fitting properly and providing optimal vision.

In conclusion, scleral lenses can be an excellent option for people with irregular corneas or other eye conditions that make it challenging to wear standard contact lenses. While the cost and fitting process may be more involved than for traditional contact lenses, the benefits in terms of comfort, vision, and protection can be well worth it. If you are interested in scleral lenses, talk to your eye doctor to see if they are a good option.
