Abstract
Purpose: This study assesses the knowledge and attitudes of dermatologists in Saudi Arabia with regard to dry eye disease, refractive surgery, and contact lenses when prescribing isotretinoin.
Methods: A total of 150 dermatologists from major cities in Saudi Arabia were included in this cross-sectional study. Data were collected through a consent interview questionnaire.
Results: Of the 150 dermatologists who participated, 77 (51.3%) were men. Seventy-three (48.3%) dermatologists always prescribed isotretinoin to patients and 71 (47.3%) sometimes prescribed it. One hundred forty-six (97.3%) dermatologists self-reported their awareness of the ocular side effects of the drug. One hundred twenty (80.0%) responded that it was not important to refer patients to an ophthalmologist for an eye examination before starting the isotretinoin course. Lubricant eye drops were routinely prescribed by 96% of the respondents during the isotretinoin course. Fifty (33.3%) dermatologists rarely or never asked patients about recent refractive surgery before starting the isotretinoin course. Sixty-six (44%) dermatologists rarely or never warned their patients to avoid refractive surgery for at least 6 months after the isotretinoin course is completed. One hundred ten (73.3%) dermatologists always informed their patients of contact lens intolerance as a result of isotretinoin use.
Conclusion: Almost all participants prescribed lubricant eye drops routinely. Most participants self-reported their knowledge regarding the ocular side effects of isotretinoin; however, more than a third did not inquire about recent refractive surgery before starting the course, and less than half did not warn patients not to undergo refractive surgery 6 months after the end of the course. This demonstrates that a significant proportion of dermatologists do not follow the appropriate practices with respect to refractive surgery when they prescribe isotretinoin. Improving the dermatologists' awareness regarding isotretinoin prescription practice is essential with respect to laser refractive surgery to prevent ocular damage.
