My father aged 64 had been advised to undergo cataract surgery. After all the scans and blood test it's observed that everything is normal. My father has hyper tension and thyroid for which he is taking tablets from past 2 years. Now the hospital has given us options to select lenses among three monofocal lenses which are : Alcon SN60WF IQ, J&J Tecnis 1 ZCB00 and zeiss CT LUCIA 611P/PY. I am a bit confused which one to go for. It will be of great help if someone helps me with this. Thanks in advance PS: I read in somewhere that PATIENTS face problems of eye lens flickering or dysphotopsia when they have undergone cataract surgery with Alcon sn60wf IQ lens.
