The camera cannot see through to the retina if the cataract is severe.
Depending on your age, you may consider getting the cataract fixed. I got one eye fixed 3 years back, as today its more or a less a standard routine with a very high success rate. It literally only takes a few minutes and its done with micros surgery, needing only like 3-5 mini-stitches that all just dissolve by themselves over a couple of days after the intervention. I too waited for maybe 4-5 years until my vision on the right eye no longer served any use, as the cataract became more severe. Amazing the clarity and light I now see with that eye, much better even than the other eye (with no cataract so far). Prognosis is that I will not need any further procedures on that eye for the rest of my life, so clearly worth doing while still being able to benefit from added pleasures in life.
