Increasing Prevalence of Myopia and Presbyopia to Boost the Demand for Myopia and Presbyopia Treatment

 

Myopia and presbyopia are terms that represent dysfunctionality in the eyes. Myopia is the most common cause of impaired vision in individuals under age 40 while presbyopia is the normal loss of near focusing ability that occurs with age. Presbyopia occurs in individuals aged between 40 to 50 years. Myopia and presbyopia treatment includes medication and surgeries or can be corrected with glasses or contact lenses.

The increasing prevalence of myopia and presbyopia worldwide is increasing the demand for safe and effective myopia and presbyopia treatment. Over the years, myopia and presbyopia have become common ocular disorders in Japan among school children. The symptoms of myopia and presbyopia include headaches, eye strain, squinting, etc. Moreover, eye drops containing medication are also emerging as myopia and presbyopia treatment. In older adults, presbyopia becomes more frequent, they need glasses to read the small print.

Myopia and presbyopia can be diagnosed by a basic eye exam, which includes an eye health exam and a refraction assessment, which determines if an individual has presbyopia, myopia astigmatism, or farsightedness. A doctor may use various instruments and ask to look through several lenses to test near and distance vision. Options for myopia and presbyopia treatment include wearing contact lenses or spectacle lenses (corrective eyeglasses), getting lens implants for presbyopia, or undergoing refractive surgery.

Refractive surgical procedures include Conductive keratoplasty, Laser-assisted subepithelial keratectomy (LASEK), Laser-assisted in situ keratomileuses (LASIK), and Photorefractive keratectomy (PRK). Refractive surgery reduces the need for eyeglasses and contact lenses and improves close-up vision. However, one may need eyeglasses some of the time even after the surgery. LASIK and other techniques used for treating myopia and presbyopia condition is rising steadily. As these two vision impairment conditions are relatively common, many ophthalmologists are continuously finding ways to develop better techniques to handle these conditions. To date, a large number of these techniques have been developed and are currently undergoing clinical trials to find improved results.
