My vision was clear after catarct surgery but now i'm experiencing vision that does not seem clear in left eye. had yag laser but still not clear ?

Need more info: If yag laser was completed, and opening adequate, the the other issues would be......Need for glasses , clarity of the cornea, and/ or the functioning of the macula in the back of the eye. Talk to your ophthalmologist

Check the retina: After cataract surgery and even after nd:yag capsulotomy, the eye can develop cystoid macular edema or cme. Cme can develop typically four to eight weeks after cataract surgery or yag. It results in a dulling or blurring of the central vision caused by swelling of the retinal tissue. It is very treatable if caught early. See a retinal specialist. www.asrs.org.

Need retinal exam: I would ask to have an oct performed on your retina. Macular edema can cause a decrease in vision after cataract surgery

Need evaluation: If your postoperative vision is decreasing despite attempts to correct it, you need an examination of your eye. A careful refraction is important. An exam of the iol, cornea and anterior chamber for inflammation assessment, and a dilated retinal examination is also extremely important. Sometimes anti inflammatory eye drops for edema in the macula occurs after cataract surgery and can be reversed.
