DS hasn't retested after his vision has settled in, but easy home tests like finding a pair of socks on the floor are now possible (by possible, meaning if he thinks about it, preferably without a reminder.)
We may find out soonish as it has been almost two years since his IQ test, and he may need to retest to enter a program. Of note is his first IQ test was immediately after his patch therapy ended. So, in theory, with two years he may have caught up, but it is also possible the vision related cognition is still tracking behind relative to kids his age who have had 9 years of normal vision to build those skills.
