Summary

Atopy significantly increases the risk of diffuse lamellar keratitis (DLK) after LASIK surgery. Preoperative treatment for atopic patients can reduce DLK incidence and potential vision loss.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Allergy and Immunology

Background:

  • Diffuse lamellar keratitis (DLK) is a potential complication following laser in situ keratomileusis (LASIK).
  • Patient-specific factors may influence the development of DLK.
  • Atopy, a predisposition to allergic diseases, has been investigated as a potential risk factor.

Purpose of the Study:

  • To determine if atopy is a patient-specific risk factor for developing DLK after LASIK.
  • To assess the impact of preoperative antiallergy medication on DLK incidence in atopic patients.

Main Methods:

  • Retrospective survey study design.
  • Inclusion of 360 consecutive patients undergoing primary bilateral myopic astigmatic LASIK.
  • Data collection on patient self-reported atopy and allergy medication use via preoperative questionnaires.

Main Results:

  • Untreated atopic patients exhibited a significantly higher risk of DLK compared to non-atopic patients (OR, 5.85; P = 0.001).
  • Atopic patients treated with systemic nonsedating H1 antagonists showed no significant difference in DLK risk compared to non-atopic patients (OR, 0.54; P = 0.43).

Conclusions:

  • Atopy is identified as a patient-specific risk factor for DLK post-LASIK.
  • Preoperative treatment in atopic individuals is recommended to minimize DLK incidence and prevent visual impairment.
  • This finding highlights the importance of considering patient allergy status in LASIK procedures.
