Before the surgery, everything was explained in painstaking detail. The operations were completely pain-free and the immediate after-effects were exactly as described: instantly clearer vision and greater brightness and colour intensity. I did experience a high degree of smarting and watering of both eyes for several days, which Professor Gartry ascribed to a rare allergic reaction to the eye drops – he changed these , with very quick elimination of the problem. Everything has now settled down perfectly and I have excellent vision in both eyes, with no need for contact lenses or reading glasses any more. Truly life-changing!
