Glaucoma Surgery

A laser aimed at the eye's drainage meshwork, through a contact lens, in the clinic. It takes five minutes, needs only numbing drops, and the patient goes home at once. The LiGHT trial randomized 718 newly diagnosed patients in the United Kingdom to laser first or drops first. At three years, 74.2 percent of the laser group needed no drops to keep their pressure at target, eleven patients in the drops group needed glaucoma surgery against none in the laser group, and quality of life was the same.

The effect fades over years in many eyes and the laser is repeatable. It suits open-angle glaucoma and raised pressure without advanced damage, and it is the first step for many patients who would otherwise face drops for life.

Surgeons place several kinds of tiny device in the drainage channel through the same opening used for cataract surgery, adding a few minutes to the operation. In a randomized trial of 240 eyes with mild to moderate glaucoma, 72 percent of eyes that received a trabecular micro-bypass stent with their cataract surgery kept a pressure of 21 or below without drops at one year, against 50 percent with cataract surgery alone, and the safety profile matched cataract surgery.

These devices lower pressure modestly and reduce the number of drops a patient needs, which for someone struggling with three bottles a day is a real gain, while advanced glaucoma needs a larger fall than they give.

Trabeculectomy can drain too much in the first weeks, leaving a soft eye with blurred vision, or too little if the channel scars. The raised bleb under the upper lid can leak, and it carries a small lifelong risk of infection that can threaten the eye, so a red, sticky eye at any time afterward is an emergency. Cataract develops faster after the operation.

Tubes can also drain too much early on, and later the tube or plate can wear through the covering tissue or shift, needing a repair. Some patients notice double vision from the plate near the eye muscles. Both operations aim at a lower pressure, and both carry the risk of needing another operation, 9 percent after tubes and 29 percent after trabeculectomy over five years in the TVT study.

After trabeculectomy the surgeon adjusts the flow through the new channel during the first weeks, loosening or cutting stitches with a laser, and may inject antiscarring medicine around the bleb. Visits come every few days at first. Drops for inflammation and infection continue for several weeks, while glaucoma drops in the operated eye stop for the majority.

Tubes follow a similar course. Checks come frequently while the tube starts to drain. Avoid heavy lifting, bending and rubbing for several weeks, and wear a shield at night, because a bleb or a freshly placed tube is at its most vulnerable while the tissues around it are still healing and a single hard rub can undo what the first weeks of careful adjustment have built.

Laser needs two to three days. That covers the assessment, the laser and pressure checks an hour and a day afterward. A micro-stent with cataract surgery follows the cataract schedule, four to five days for both eyes. Trabeculectomy and tubes need two to three weeks. Fly after the early checks. No gas is placed in the eye. The pressure decides the date of return.

The procedure decides most of it. Laser costs least, a micro-stent adds the device to the cataract fee, and trabeculectomy and tubes include the operation, the antiscarring drug or the implant, and several weeks of follow-up visits, which are the part quotes leave out most. Packages published by Istanbul hospitals quote trabeculectomy and drainage valves separately, and some describe a two-day stay for trabeculectomy that leaves no time for the checks that decide the result. Ask how many follow-up visits the price includes. Your own figure follows the free review of your tests.

One coordinator stays with you from the first message. The team works in English, Arabic, French, Russian, Serbian, Romanian and Spanish, and other languages are interpreted on request. An invitation letter naming the hospital and the surgeon goes out ten days before travel, and the international patients office arranges the airport transfer and a hotel or apartment near the hospital for you and a companion, which for a stay of several weeks matters. Halal, vegetarian and diabetic meals are available, there is a prayer room, and a request for a female doctor is passed to the department and met wherever the rota allows. Back home, the coordinator stays reachable on the same WhatsApp number, and the report goes to your own ophthalmologist, since glaucoma needs lifelong monitoring whatever operation is done.
