The surgeon replaces the cloudy lens with a clear artificial lens. The NHS says surgery usually takes 20 to 45 minutes under local anaesthetic, you are awake but feel no pain, and most people go home the same day. Eye drops are needed for about four weeks, and serious complications are rare. The NEI reports that 9 out of 10 people who have cataract surgery see better afterwards.<\/p>\n<p data-reveal><strong>Glaucoma: lowering pressure, for life.<\/strong> Every glaucoma treatment, from drops to surgery, aims to lower eye pressure to protect the optic nerve. The AAO describes the usual order: daily eye drops first; laser (trabeculoplasty to improve drainage in open-angle glaucoma, or iridotomy for narrow-angle glaucoma); then surgery such as trabeculectomy or a drainage device if those are not enough. Treatment can stop damage getting worse but, in the words of the NEI, it will not undo damage already done. Patients are usually reviewed every few months, and drops must be used as prescribed.<\/p>\n<p data-reveal><strong>When the two meet.<\/strong> The AAO notes that in people with narrow drainage angles, removing the eye&#8217;s natural lens can itself lower eye pressure. So if you have both a cataract and glaucoma, your surgeon may plan the cataract operation with your pressure in mind. This is a decision for an examining surgeon, not something to assume from an article.<\/p><div class=\"links-row\" data-reveal><a class=\"link-arrow\" href=\"https:\/\/laseristanbulclinic.com\/en\/cataract-surgery-turkey\/\">Cataract surgery in Turkey: how it works, what it costs and who operates <svg width=\"18\" height=\"18\" aria-hidden=\"true\"><use href=\"#i-arrow\"\/><\/svg><\/a><\/div><\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><\/section>\n<!-- Image + Text (Image left, text right) End -->\n\n\n<!-- Cards (Feature cards: 2 columns) Start -->\n<section class=\"panel\" id=\"who-needs-which-check-up-or-treatment\">\n\t<div class=\"container-fluid px-0\"><div class=\"row g-0\"><div class=\"col-12\">\n\t\t<div class=\"sec-head is-center row\"><div class=\"col-12\"><h2 class=\"t48 sec-title\" data-reveal>Who needs which check-up or treatment?<\/h2><\/div><\/div><div class=\"features two row row-cols-1 row-cols-md-2\" data-stagger><div class=\"col\"><div class=\"feat h-100\"><span class=\"feat-icon\" aria-hidden=\"true\"><svg width=\"26\" height=\"26\" aria-hidden=\"true\"><use href=\"#i-lens\"\/><\/svg><\/span><h3>See an eye specialist about a cataract if\u2026<\/h3><p>The NHS says you do not need surgery immediately: stronger glasses and brighter light can help for a while, but over time cataracts get worse.

Hotel and airport transfers are not included; they are a separate charge, arranged on request. Flights are not included.<\/em> In the NHS, cataract surgery is free at the point of use, but about 650,000 people in the UK are waiting, with a median wait of 41 weeks, and the NHS does not pay for premium lenses.<\/p>\n<p data-reveal><strong>Standard vs premium lens, and toric vs regular.<\/strong> The lens you choose changes the price more than anything else. According to the AAO, the monofocal lens is the most common: it focuses at one distance, usually far, and you wear glasses for reading. Premium options include multifocal and extended depth-of-focus (EDOF) lenses, which give both near and far focus, and toric lenses, which also correct astigmatism (an uneven curve of the cornea or lens). A regular monofocal lens does not correct astigmatism, so glasses or a toric lens are needed for that. Trifocal lens replacement in Istanbul is typically advertised at $3,400\u20137,000 for both eyes. Your surgeon will recommend a lens after measuring your eyes.<\/p>\n<p data-reveal><strong>Glaucoma treatment:<\/strong> from <span class=\"ph\">{{price}}<\/span>, confirmed in writing after your surgeon reviews your case.
