After LASIK surgery to try to reduce the need for glasses, typically done in young near-sighted people, patients can experience something called “transient light sensitivity syndrome” (TLSS). This syndrome is not deeply/well understood, but it boils down to this situation: a patient who has had LASIK has good vision and a normal looking eyeball but has a lot of light sensitivity. Conditions like this can be very frustrating in which we as ophthalmologists are not really sure what’s going on because “everything looks good,” but fortunately TLSS usually gets better with steroid eye drops.
