Allergic conjunctivitis as a risk factor for laser in situ keratomileusis

Area of Science:

• Ophthalmology
• Refractive Surgery
• Corneal Surgery

Background:

• Allergic conjunctivitis (AC) is a common condition affecting the eyes.
• The impact of AC on the outcomes of refractive surgery, specifically LASIK, requires thorough investigation.

Purpose of the Study:

• To investigate the effect of pre-existing allergic conjunctivitis (AC) on the outcomes of laser in situ keratomileusis (LASIK).
• To determine if AC is a risk factor for complications or reduced visual outcomes after LASIK surgery.

Main Methods:

• A comparative study was conducted at Minamiaoyama Eye Clinic, Tokyo.
• Patients undergoing LASIK were divided into two groups: those with AC (allergic group, 84 eyes) and those without AC (nonallergic group, 140 eyes).
• Preoperative and postoperative uncorrected visual acuity (UCVA), refraction, and intraoperative/postoperative complications were compared between the groups.

Main Results:

• No significant differences in UCVA or refraction were observed between the allergic and nonallergic groups.
• The allergic group experienced no complications during or after LASIK surgery.
• The nonallergic group had instances of intraoperative conjunctival chemosis and a postoperative epithelial defect leading to epithelial ingrowth.

Conclusions:

• Allergic conjunctivitis (AC) does not appear to be a risk factor for LASIK outcomes.
• LASIK surgery can be safely performed in myopic patients with allergic conjunctivitis.
• The study suggests that careful preoperative assessment can mitigate potential risks in patients with AC.
