Dr Troski studied medicine in Melbourne and commenced specialty training in ophthalmology at the world famous Moorfields Eye Hospital in London. He completed this training at the Royal Victorian Eye and Ear Hospital.

After completing his specialist studies, Dr Troski joined his father's ophthalmic practice, which was established by his father in Collins Street, Melbourne in the 1950's. The clinic’s location is central to patients throughout Victoria, being accessible by both private and public transport.

Dr Troski is a member of the American Society of Cataract and Refractive Surgeons and is also a foundation member of the Australian Society of Cataract and Refractive Surgeons.

Dr Troski specialises in cataract surgery and has been performing cataract operations for over a decade. He performs many hundreds of cataract operations each year. Dr Troski provides a "boutique approach" to cataract surgery. He feels it is important to treat each patient individually and for each patient and their family to be comfortable with the surgical procedure.

At his Collins Street practice, Dr Troski has two full time office staff to assist patients with any questions regarding cataract surgery, and two dedicated Orthoptists who are actively involved in the process of calculating and correlating surgical results. The continuous review of surgical results by Dr Troski and his staff has been proven to optimise surgical outcomes. He also takes an active interest in modern developments in ophthalmic surgery so that patients have the benefit of all the latest worldwide techniques.
