Q: A couple of months back I had a successful cataract operation on my left eye. As instructed I applied Maxitrol eye drops for six weeks. My sight has improved greatly. However, I feel slight itching and dryness in the lower eyelid near the outside. There is also slight swelling, which makes the operated eye look smaller that the other one. I had been re-examined seven weeks later but the surgeon told me there was nothing wrong and advised me to use some eye drops. I have been applying Sodium Cromoglycate drops since then, but there is no improvement; even almost thirteen weeks after the operation. I will be obliged for your opinion.

A:There is nothing to worry about this itching. The cause is likely to be allergy and with so much dirt about. I would advise you to wash your eyes with clean water every morning and when the eye itches, but avoid itching if you can. You can also use artificial tear drops, but sometimes you can also develop allergy to the preservatives, which is are used in most eye drops.
