First of all, I suggest you should not mix two medicines at once. It can have adverse effects to the fish and the biological filtration. Second, what are your water parameters right now? Use API liquid test kit and determine your ammonia, nitrites and nitrates. Please post the exact figures. Third, do a major water change of 60-70% and use activated carbon to completely remove the medicines out of your tank. Do 30-40% water change on daily basis afterwards. Drastic for some people but this is my way of ensuring the water parameters are ideal for the fish. At this rate, I can assume your ammonia and nitrites are already present in your tank. Dilution via water changes is the only way to really prevent intoxication.
To explain further, cloudy eyes are a result of poor water quality. This is brought by the medicines you use damaging the biological filtration. Do not treat your fish unless you determine the exact cause. You need to plan the treatment course very well.
