Laser Sight Essex operate a mobile VISX laser, moving between Southend, Chelmsford & Brentwood. If I'd known about them sooner I'd have looked into it further, but they are not that well advertised and I'd already booked with Accuvision. In fact I only found out about them through personal recommdations of their surgeons, Mr Aggerwal and Mr Kasaby. Both were highly praised by trusted friends, so that should be reason in itself to check them out, especially if you're in the Essex area and don't want to travel up to London. www.lasersightessex.com, or 01702 588 999.
