[8] [10] Any fluid behind the retina is drained, and tears are sealed with freezing or lasers. [8] [10] The removed vitreous is then replaced with either a gas bubble or silicone oil, which stabilizes the retina.
Nearly all ocular surgeries viz keratoplasty, cataract extraction, glaucoma surgery, iridectomy, strabismus, [5] retinal detachment surgery etc. can be done under regional anaesthesia. Conjunctiva, globe and orbicularis can be paralysed using a combination of surface anaesthesia, facial anaesthesia and retrobulbar block. [1]
When the cornea dries out it may stick to the eyelid and cause an abrasion when the eye reopens. [11] Exposure keratitis. Chemical injury can occur if cleaning solutions such as povidone-iodine (Betadine), chlorhexidine or alcohol are inadvertently spilt into the eye, for example when the face, neck or shoulder is being prepped for surgery.
