ORTHOKERATOLOGY: WHY WEAR LENSES ONLY AT NIGHT?

The reversible procedure, developed for those with minor myopia and/or astigmatism, includes wearing lenses at night to alter the cornea’s curvature and get a corrected vision the following day. Do you think it’s effective?

Orthokeratology is a non-invasive approach to correcting eyesight while you sleep. As a result, orthokeratology lenses aid in the correction of mild to severe myopia or astigmatism. In order to make up for an optical flaw, wearing lenses at night is advised. It is also possible to see clearly throughout the daytime without the need for any adjustment. Changes in corneal curvature are key to this method. An alternative to refractive surgery is orthokeratology, which has progressed significantly in the previous ten to fifteen years and can be a viable option.

What is orthokeratology, and how does it differ from regular contact lenses?

In the early 1960s, orthokeratology made its initial steps. At night, use flexible lenses as part of this strategy. When a result, myopia is reduced or eliminated entirely during the daytime hours as the cornea is flattened.

In what ways does orthokeratology work?

Ortho-K makes use of lenses that are semi-rigid but have a predetermined form on the inside: There is a way to manipulate this normal movement of epithelial cells in order to achieve our desired result… Periphery becomes thicker and core becomes thin… At around 5.5 mm in diameter, the cornea’s surface is less curved. The cells at the base of the body remain unchanged.

In reality, there is no danger of fracturing the cornea. This process is reversed during the day when epithelial cells renew and return to their former location. Visual acuity of 10/10 may be maintained the next day, or even the day after tomorrow, with a nocturnal sleep of seven hours or fewer.

How might orthokeratology lenses help those who suffer from dry eyes?

Myopia up to 4D and astigmatism up to 2.5D can be corrected using orthokeratology lenses, if necessary. A viable alternative to surgery for individuals who wish to be free of glasses or lenses throughout the day but don’t want or can’t have surgery, especially if there are warnings or the view isn’t stable. Even though standard lenses have been completed, they can still be utilized. Those who work with water or dust are particularly interested. Firefighters, rugby players, swimmers, surfers, and pelota players on skis were all in the area where he was exercising.

As it develops, a system

It has been around since the 1960s. Opticians and other non-medical experts were the only ones who could perform the procedure for a long period. Ophthalmologists took extra precautions due to the fact that they were unsure of how corneal alterations occurred.

Then the measurement devices are in great working order. Custom lenses may now be offered thanks to the high level of tolerances they have in place. Material properties such as biocompatibility and permeability have improved as well.

Contacting a qualified optician optometrist– contact expert in ophthalmology is a must. Opticians are not allowed to prescribe or fit any sort of lens. To ensure there are no contraindications, he or she does corneal measurements and orders lenses at the initial visit.
