Hi Tim. The pain you are experiencing following a complicated cataract
extraction and retinal surgery
has a few causes. The first one that needs to be looked into considering you have/ had silicone oil injected in the vitreous cavity coupled with retained lens
material is a raised intraocular pressure
or eye pressure. This is very common in a situation such as yours and has to be measured early to make sure there is no damage on the optic nerve
. High pressures can be treated with eye drops till the lens matter absorbs.Secondly , you may be having uveitis
or an inflammation of the eye due to surgery itself and the manipulation involved or due to retained lens particles. This can be treated with steroid
eye drops and dilating drops to give you relief. An ideal treatment for the lens matter left in the eye would be to have the vitreoretinal surgeon remove it. However, small cortical matter can be left behind and observed keeping a watch on the inflammation and eye pressure. Consult your ophthalmologist who will check the intraocular pressures and inflammatory signs and chart out a treatment plan accordingly. Once these are attended to the pain subsides. You may take an oral pain reliever for the time being for temporary relief.
