COMPLICATIONS OF REFRACTIVE SURGERY
Particular complications to each surgical procedure :
Radial keratotomy
• Visual fluctuations
• Photophobia and night halos
• Secondary or progressive hyperopia
• Theoretical weakening of the eye
PRK Lasek
• Post-operative pain from 2 to 3 days
• Late healing of the epithelium
• Haze or sub-epithelial cicatrisation inducing a blur vision which decreases over time: 1% to 2%
• Night halos if high myopia, high pupillary diameter or haze
• Low risk of postoperative infection: 1/4000
Lasik
• Decentration of the corneal flap during first post-operative days: patient must wear an eye-cover at night during 2 weeks after surgery
• Dry eye: regular use of artificial tears is necessary during the first post-operative month
• Epithelial ingrowth in the interface under the corneal flap (0.1%) avoided by rinsing
• Inflammation under the corneal flap (0.5%) requiring anti-inflammatory treatment or rinsing the interface
• Night halos if high myopia or large pupillary diameter
• Extremely low risk of postoperative infection: 1/5000
Aberrometry:Customized wavefront treatment with aberrometry by Lasik or PRK:
• Same complications reported in Lasik
• Less regression and retreatment (2%-3%). Usually, a retreatment free of charge is necessary in 4 to 5% of cases
Less Glare and night halos.
