Months or years after cataract surgery, your vision may become blurry again. Laser often provides excellent vision recovery. When the posterior capsule (behind the intraocular lens) becomes opaque, a small hole is made with a laser. Generally, vision improves dramatically.
Vision problem
The cataract is surgically removed and the intraocular lens is placed in front of the posterior capsule, providing support from it. Then, over time, the posterior capsule becomes thicker, preventing light from reaching the retina and seeing clearly.
Laser
With the Yag photodisruptive laser, the posterior capsule is opened to create a small opening. This opening allows light to pass through without any obstacles and improves vision.
GLAUCOMA
Laser can prevent serious vision loss due to glaucoma, especially in patients over 40 years of age. Open-angle glaucoma is a disease that can lead to chronic, normal or progressive vision loss leading to total blindness. Closed-angle glaucoma is acute, the blocked fluid can lead to a sudden increase in intraocular pressure, severe pain and permanent vision loss. Laser reduces pressure, reduces pain and protects vision. Second treatment may be required.
Vision problem
Open angle: Fluid cannot drain out of the eye. Eye pressure rises and optic nerve fiber damage and vision loss gradually occur.
Closed angle: The drainage angle between the iris and cornea narrows or closes. The fluid cannot drain, causing the pressure to rise.
Laser
Open angle: When pressure cannot be controlled with medications, argon laser is used to open the trabecular network.
Closed angle: Medication is given to reduce the pressure, then small openings are created in the iris with the argon laser.
What You Will Feel
Open angle: The treatment is painless. Pressure is checked on or about that day. There is no activity limitation. The medication is continued until control.
Risk: Glaucoma may not be controlled.
Closed angle: Treatment is usually painless. Pressure is checked on or about that day. vision protection lyre. You can do your normal activities. The medication should be continued until the check-up.
Risk: Light bleeding, usually disappears on the first day.
MACULA DEGENERATION
Macular degeneration over the age of 50. It is a disease that affects both eyes (rarely simultaneously), especially in people over 70 years of age. Central vision and color vision may be impaired. Get yourself tested at an early stage when laser treatment is still possible. While laser can help in this situation, surgery cannot. The natural course of macular degeneration is loss of near vision. Laser offers some patients with this condition the chance to recover or preserve vision.
Vision problem
New abnormal vessels form in the retina, under the macula, and fluid and lipid leakage occurs. . These leaks lift the retina, affecting sharp vision (localized in the fovea) and color vision. This results in a gray and distorted image.
Test
Fluorescein angiography, Amsler grid (to determine where the vision is sharp and where it is distorted) and Optical Coherence Tomography ( OCT). If the tests show that you can benefit from laser, treatment is planned.
RETINAL TEAR
Retinal tear can occur at any time. Suddenly, spots, flies, or flashes of light may appear in one eye. You should have your eye examined immediately so that fluid does not enter under the tear and cause retinal detachment. Early laser treatment allows you to return to your activities as soon as possible.
Vision problem
A horseshoe-shaped tear in the retina can cause small vessels to rupture, causing bleeding into the vitreous. If left untreated, the tear may cause retinal detachment and may require surgery.
Laser
Your doctor aims to prevent retinal detachment by covering the edge of the tear with several rows of lasers using laser photocoagulation. This also prevents flies from increasing.
RETINA VASCULAR OCCULATION
If you are middle or elderly, have high blood pressure, and newly formed one-sided vision If you have loss, retinal vein occlusion may have developed. Although treatment is not required in the very early stages, regular check-ups are essential.
Vision problem
Retinal vascular fluid and becomes clogged with blood. Retinal hemorrhages near the vessel, edema in the macula, and abnormal new vessel formation (neovascularization) may occur. If vessels form in the front part of the eye, neovascular glaucoma may develop.
Laser
Tests are performed for vision and pressure. The results are evaluated at regular intervals. If there is nothing new, surgery is not required. If available, a laser plan is made. For macular edema, laser is applied in the form of a grid or to the area of newly formed vessels.
What You Will Feel
The laser dries the fluid, burns the new vessels and improves vision. It is a short outpatient procedure. You can return to your daily activities immediately. Your doctor will tell you the check-up date. Risk: Vision may not improve.
The past, present and future of laser
Laser has been used on the eye since the 1970s. Today, it is used in the treatment of diabetic retinopathy, glaucoma, macular degeneration, retinal tear, retinal vein occlusion and in opening the posterior capsule occlusion that occurs after cataract surgery. It is still used for refractive error correction.
