Good afternoon Sophie,
There are no direct correlations between a developed twitch in the eye and laser eye surgery so it shouldn't be an issue (in relation to surgery). It is an involuntary movement of the eyelid with a many number of things that could have caused its development. If it continues to get worse by all means come in and see us and we can have a look at the eye. We may refer you from there.
If you have any questions please call me on 01733 297 193 or email david.knight@optimax.co.uk.
Kind regards,
David.
