Presbyopia happens to most people at some point during their lifetime, regardless of wearing glasses. This condition usually begins at 40. Interestingly, those who wear glasses for myopia correction do not feel it happen.
Presbyopia is caused by the loss of accommodation in the eyes. As one ages, the natural lens loses its quality, power, and elasticity. Thus, the eyes cannot perform the required accommodation. This condition usually begins at early forties, and reaches its climax at late fifties. Patients with premature presbyopia are those with a history of hyperopia or severe myopia who are used to reading and doing close-up work without glasses. Patients with diabetes or certain other diseases may also face premature presbyopia.
With the advent of novel technologies, ophthalmologists have succeeded in placing certain tools inside the cornea using laser in order to correct accommodation, a technology which is known as “corneal inlays”.
This method is effective for those aged 45-70 who have had laser eye surgery for spectacle removal or cataract treatment, and do not wish to wear glasses. This method has been implemented in Iran for years. Globally, however, it has a slightly longer history, helping tens of thousands to control and treat presbyopia.
Corneal inlays ensure vision for life. In normal cases, since it has no diopter and enhances the eyes’ depth of field by a physical property, this technology offers an effective and successful treatment. However, if the eyes’ optics changes by, for instance, intra-ocular surgery, glaucoma, or accidents, new refractive errors occur and change the story.
