It is not always easy to determine how your baby or young kid can see. For this reason, experts in paediatric ophthalmology have devised various electrodiagnostic means to detect vision problems in the young. They include the VEP and ERG tests. These initials stand for ‘visual evoked potential’ and ‘electroretinogram,’ respectively. An eye doctor in London will use these tests to learn about how the pathway from the eye to the brain via the retina is working. Now, there is no reason not to take your toddler to an eye specialist as there are two effective means to detect vision problems early on.

Laser eye surgery is becoming a popular method for correcting visual impairments such as myopia, hyperopia and astigmatism. There are various different procedures available and LASIK, or laser-assisted in situ keratomileusis, is probably the most common. What does it involve and what are the benefits of this surgical procedure? LASIK involves the use of a microkeratome or femtosecond laser which cuts a flap in the cornea. This flap is pulled back to reveal the stroma layer. Employing an excimer laser which uses ultraviolet light beams to remove minute amounts of the underlying corneal tissue, the cornea is reshaped to properly focus light onto the retina in order to improve vision. Once completed, the flap is put back in place and the cornea is left to heal naturally.
