Keratoconus is an eye disorder where the cornea, the clear front surface of your eyes, starts to bulge outwards. The condition can begin to occur at the age of 10-25 and progress over time. Due to the slow progression of the keratoconus, it has many treatment methods for each stage. These consist of eyeglasses, different types of contact lenses, implants, and surgical procedures. This article will give a comprehensive guide on keratoconus treatment types for your reference.
Scleral contact lenses
These lenses are specially designed with a larger diameter to support the irregular-shaped cornea. These lenses can cover the cornea surface, including the white area of your eye, to keep more stability. The sizes of these range from 14.5-24mm. The average size of the human cornea is 110.8mm, and even the smallest size of a scleral lens can cover the entire cornea. These lenses are used to treat milder forms of keratoconus and astigmatism conditions.
This is the latest and the most advanced treatment available to treat the keratoconus condition. Crosslinking can be performed in the below two methods.
Epithelium-off: Here, the outer layer of your cornea will be removed, and a type of vitamin B named riboflavin will be entered to bond collagen together. UV light is used here to activate them and anchor the cornea.
Epithelium-on: This is also referred to as transepithelial cross-linking, and here the epithelium is left intact without removal.
These are usually prescribed for patients with advanced keratoconus stages. These lenses are made using the eye print process, where the technology is used to match each eye’s irregularities. Your doctor will take an eye print and send the impression to the laboratory for the 3D scanning process. The data is then fed to create a lens that matches the irregularities of the eyes.
These are arc-shaped inserts that are placed using a surgical procedure to reshape the corneal bulge. They are used for patients who can get clear vision with eye lenses or contact lenses. Those implants can be removed or and exchanged when required. Intacs cannot prevent the progression of keratoconus and can only delay the process. Even after using intacs, patients may require a corneal transplant once they reach the final stages.
Hybrid Contact Lenses
These lenses are equipped with a combination of materials. The center of the lens is composed of oxygen-permeable rigid nature, whereas the surrounding surface is made with a soft peripheral. The lenses are available in varieties and designed to increase the comfort of the wearer. The lens center vaults over the eye’s cornea and the soft “skirt” will provide minimal discomfort when wearing the lenses.
This is the definitive treatment given for the advanced stage of keratoconus. Eye specialist recommends transplants when contact lenses and other techniques no longer support the cornea for clear vision.
The surgery involves replacing the damaged corneal with donated corneal tissue. If the entire cornea is replaced, it is called penetrating keratoplasty, where a partial removal is known as lamellar keratoplasty.
Distorted vision, increased light sensitivity, frequent change of eyeglass prescriptions, and sudden worsening of eyesight are some of the signs and symptoms of keratoconus condition.
