The most common complication of macular hole surgery is the formation of cataracts, which is why it's necessary to inform the patient of the likelihood of removing the cataract within a period of 1-2 years. From the age of 50, patients are advised to undergo combined cataract and macular surgery in a single procedure.
There are other less common complications that are comparable to those we find when performing a vitrectomy for another reason such as tears, retina detachment or intraocular infections.
