Purpose:
To demonstrate that patients undergoing LASIK retreatments generally have good uncorrected vision and small refractive errors prior to retreatment surgery.
Methods:
A list was generated of all refractive surgery retreatments performed in our four laser centers from August 2003 to July 2004. From this list, a total of 100 patient charts were randomly chosen. Only eyes that had full distance correction with LASIK as the primary surgery were included. The last uncorrected visual acuity (UCVA) and manifest refraction spherical equivalent (MRSE) prior to retreatment were recorded.
Results:
For a total of 109 eyes studied, the average UCVA prior to retreatment was 20/36. Eighty-one percent (88/109) of the retreated eyes were already seeing > or = 20/40. The average MRSE prior to retreatment was -0.43 +/- 0.98 D.
Conclusions:
The majority of patients receiving LASIK retreatments have relatively good uncorrected vision and minimal refractive errors prior to retreatment.
