The prevalence of myopia has been reported as high as 70–90% in some Asian countries, 30–40% in Europe and the United States, and 10–20% in Africa. [128] Myopia is about twice as common in Jewish people than in people of non-Jewish ethnicity. [130] Myopia is less common in African people and associated diaspora. [127]
The condition of posterior staphyloma in high myopia was first described by Scarpa in the 1800s. [6] Speculation about reinforcement of the eye began in the 19th century, when Rubin noted that sclera reinforcement “is probably the only one of all the surgical techniques [for myopia] which attempts to correct a cause, rather than an effect”. [7]
All represent advances over radial keratotomy in the surgical treatment of refractive errors of vision. For people with moderate to high myopia or thin corneas which cannot be treated with LASIK or PRK, the phakic intraocular lens is an alternative. [4] [5]
Fuchs spots are caused by regression of choroidal neovascularization. [3] Since it is a medical sign, treatment is given for the actual cause. Photothermal laser ablation, photodynamic therapy, anti-VEGF therapy, or a combination of these are the treatment options of choroidal neovascularization due to pathological myopia.
In some people with very high myopia, the eye may be left aphakic, without intraocular lens implantation. [16] A related procedure is the implantation of phakic intraocular lenses in series with the natural lens to correct vision in cases of high refractive errors. [17]
The boy, who required eyeglasses for correction of myopia caused by astigmatism, fell off his bicycle. His glasses shattered on impact, and glass particles lodged in both eyes. To save the boy's vision, Fyodorov performed an operation which consisted of making numerous radial incisions extending from the pupil to the periphery of the cornea in ...
Laser blended vision is a laser eye treatment which is used to treat presbyopia (ageing eyes; [1] progressive loss of the ability to focus on nearby objects) or other age-related eye conditions. [1] It can be used to help people that simply need reading glasses, and also those who have started to need bifocal or varifocal spectacle correction ...
A 2016 systematic review found that it was unclear whether there were any differences in efficacy, accuracy, and adverse effects when comparing PRK and LASEK procedures among people with low to moderate myopia. [18] The review stated that no trials have been conducted comparing the two procedures on people with high myopia. [18]
