LASIK and isotretinoin: An important contraindication
Sir - We enjoyed the informative review on laser refractive eye
surgery and wish to raise awareness of a potential hazard with concurrent
Isotretinoin (13-cis-retinoic acid) has revolutionised the treatment
of refractory acne since the 1980s. Acne affects 85-90% of the population
at some time and the age of patients affected by acne approximately
overlaps that of patients undergoing LASIK (2,3). Dry eye is a side effect
of both LASIK and isotretinoin (4-6) and can result in serious sequelae
such as corneal ulceration, infection and loss of vision. Thus, LASIK is
contraindicated in patients taking isotretinoin (2,7), but this fact is
not well recognised, especially amongst British Dermatologists who
prescribe Isotretinoin. Previous surveys have highlighted the need to
routinely screen for isotretinoin use before approving LASIK and have
concluded that patients should wait 6 months after a course of
isotretinoin before having refractive eye surgery (8).
We recently surveyed the British Association of Dermatologists.
Although most physicians routinely counselled their patients about the
ophthalmic risks of isotretinoin, 65% did not know whether any of their
patients had undergone LASIK whilst on isotretinoin, only 30% enquired
about recent or forthcoming surgery and 89% were unaware that isotretinoin
may cause ocular problems if a patient had undergone LASIK in the
preceding 6 months.
Patients should avoid isotretinoin 6 months before or after LASIK
treatment. Similarly LASIK practitioners should check that isotretinoin
has not been taken for 6 months before laser refractive eye surgery.
