Impression Scleral Lenses

The Khanna Vision Institute has established itself as a pioneer in the field of impression scleral lens solutions. As a leading keratoconus specialist, Dr.Khanna and his team have dedicated themselves to providing patients with cutting-edge, non-surgical treatment options that can dramatically improve their quality of life.

Impression scleral lenses have emerged as a game-changing solution for individuals struggling with keratoconus and other corneal irregularities. These specialized lenses are custom-designed to seamlessly fit the unique contours of each patient’s eye, providing unparalleled comfort, clarity, and visual acuity. The Khanna Vision Institute’s expertise in impression scleral lens fitting and management has earned them a reputation as the go-to destination for those seeking effective, long-term relief from the challenges of keratoconus.

Impression Scleral Lenses

Impression scleral lenses are custom-made contact lenses designed to fit the unique shape of the eye. They are particularly effective for individuals with keratoconus due to their ability to provide a stable, comfortable fit and excellent vision correction.

How Impression Scleral Lenses Works

Custom Molding:

Unlike standard contact lenses, impression scleral lenses are created based on a detailed mold of the patient’s eye. This process involves taking an impression of the cornea and sclera (the white part of the eye).

Large Diameter:

These lenses are larger than regular contact lenses and rest on the sclera rather than the cornea. This larger size helps them vault over the irregularly shaped cornea, providing a smooth optical surface.

Fluid Reservoir:

The space between the lens and the cornea is filled with a saline solution, which helps to mask the irregularities of the corneal surface, leading to improved vision. The fluid reservoir also keeps the eye hydrated and can alleviate discomfort associated with keratoconus.


Enhanced Vision:

By providing a smooth optical surface and masking corneal irregularities, these lenses offer superior visual acuity compared to glasses or regular contact lenses.


The lenses rest on the less sensitive scleral tissue, which can reduce irritation and increase comfort, especially for patients with advanced keratoconus.


They are less likely to move on the eye compared to smaller lenses, providing more consistent vision correction.

Fitting Process

Initial Assessment:

The eye care professional evaluates the patient’s eye condition and suitability for impression scleral lenses.

Impression Taking:

An impression of the eye is made using a specialized material. This impression captures the detailed shape of both the cornea and sclera.

Lens Fabrication:

The impression is sent to a laboratory where the custom lens is manufactured. This process can take several weeks.

Lens Fitting:

Once the lenses are ready, the patient returns to the eye care professional for fitting. Adjustments may be made to ensure optimal comfort and vision correction.


Regular follow-up appointments are necessary to monitor eye health and make any necessary adjustments to the lenses.



Impression scleral lenses are typically more expensive than regular contact lenses due to the custom fabrication process.

Adaptation Period:

Patients may require some time to adapt to wearing these larger lenses.


Proper cleaning and handling are essential to maintain lens hygiene and eye health.
