LASIK, blepharoplasty, and dry eyes

Area of Science:

• Ophthalmology
• Oculoplastics

Background:

• Laser-assisted in situ keratomileusis (LASIK) and blepharoplasty are common ophthalmic and oculoplastic procedures.
• Both LASIK and blepharoplasty are independently associated with the potential development or exacerbation of dry eye symptoms.

Purpose of the Study:

• To discuss the physiological mechanisms by which LASIK and blepharoplasty can induce or worsen dry eye.
• To provide practical guidelines for the clinical evaluation of patients experiencing dry eye symptoms post-surgery.

Main Methods:

• Review of physiological mechanisms related to dry eye following LASIK.
• Review of physiological mechanisms related to dry eye following blepharoplasty.
• Discussion of clinical evaluation strategies for patients with post-surgical dry eye.

Main Results:

• LASIK can disrupt corneal nerves, affecting tear production and sensation.
• Blepharoplasty can alter eyelid function and tear drainage, contributing to dry eye.
• The cumulative effect of undergoing both procedures may significantly increase the risk and severity of dry eye.

Conclusions:

• Patients considering or having undergone both LASIK and blepharoplasty require careful evaluation for dry eye.
• Understanding the combined impact of these procedures is crucial for managing patient expectations and ocular surface health.
