Dholakia Iris Hook
Dholakia Iris Hook is a set of 5 disposable iris retractors made of black nylon fibre with an adjustable silicone lock. The hook has a ‘U’ shaped bend on one end, which helps in engaging the iris and pulling it backwards to enlarge the pupil. The hook is designed in such a way that it is angled to be in the plane of the anterior capsule. The silicone lock helps in retaining the hook in retracted position during the surgery. After the surgery, the lock can be adjusted to release the iris so that it comes back to its original position.
