Yes, eye surgery can fail, although this is rare for many procedures. The success rate varies depending on the type of surgery and individual patient factors. While most cataract and LASIK surgeries are successful, complications can occur.
Types of Eye Surgery and Potential Failures
Several factors contribute to the possibility of eye surgery failure. These include the surgeon's skill, the patient's overall health, and the specific procedure itself. Let's examine some common procedures:
LASIK Surgery
- Failure Rate: While generally safe and effective, LASIK has a reported complication rate ranging from 10% to 30%, according to some analyses of industry data. The Guardian
- Potential Complications: Complications can include ischemic optic neuropathy, retinal detachment, vitreous hemorrhage, and Postoperative infectious keratitis (PISK) causing severe eye pain, blurry vision, redness, and more. Eyesight Hawaii, [Rare LASIK Surgery Risks](Rare LASIK Surgery Risks)
- Ineffective Procedures: In some cases, LASIK may not fully correct vision, resulting in less than perfect results. BD Plasik
Cataract Surgery
- Failure Rate: The vast majority of cataract procedures are successful, with a low incidence of serious complications. Desert Vision Center
- Potential Complications: Although rare, potential complications include blurred vision, eye pain, light sensitivity, photopsia (seeing flashes of light), macular edema, ptosis (drooping eyelid), intraocular lens dislocation, and post-operative infection. WebMD, AARP
- Ineffective Procedures: In rare instances, cataract surgery may not be fully effective, leading to persistent or worsening vision problems. Healthline
