Things To Do And Not To In Orthokeratology

Posted by Accuspire on Aug 23rd 2023

Orthokeratology is a method to correct vision problems. A specially designed glass permeable contact lens is used in this process, which are designed to alter corneal shape. They are to be worn during night time and removed in the morning. There is no need for wearing contact lenses or glasses during day time and one is able to view clearly. It is used to correct astigmatism and short sightedness.

Safety Guidelines for Successful Orthokeratology

Before undergoing orthokeratology, one must consider some safety guidelines. They are centration, binding or adherence, corneal staining, dimple veiling etc. in orthokeratology, lateral and vertical centration of RGP lenses is very essential. The visual acquity won’t be optimal if there is no centration. This is because the treatment zone won’t be centered on the optical axis of eye and pupil. When you wake up after wearing the lens for the first time, see your doctor within some hours to ensure proper centration. The doctor will observe the movement of lens, its fit, corneal topography and visual acquity.

Managing Potential Issues: Binding and Adherence

When there is a usage of large diameter lens, binding is possible. To avoid this one must put some drops of rewetting solution in eyes. This is to be practiced even after waking up. Alternatively, one may not remove the lens immediately after waking. If the lens has adhered, the drops may make them move spontaneously after blinking. It is also important to ask an ophthalmologist on how to loosen the lens manually if it is bounded. If you perform the above mentioned steps and still the lens is not moving freely, consult you r ophthalmologist immediately.

Patients whose eyes are not producing adequate tears, orthokeratology is not advised for them. They are susceptible to corneal staining. Air bubbles can cause indentations in epithelium between the RGP lens and cornea. This is not a serious problem and can be corrected easily. They resolve quickly when they are fitted again.

Potential Complications and Adherence

Some of the other complications of this condition which are caused because of failure to comply with the instructions given by the ophthalmologist are corneal scarring, decreased vision, iritis, redness, tearing, corneal edema, discomfort, discharge, corneal abrasion, vision distortion, neovascularization etc. if you feel these symptoms, consult your ophthalmologist immediately and don’t use the lens till the ophthalmologist says you to wear it.
