3 Audits: All patients

4 Age Distribution

5 Audits; All Surgery types- All patient types

6 Audits: All surgery types-Myopes

7 Audits: All Surgery types- Hyperopes

8 number of eyes pre OP: 1160 average 35 years (from 18 to 66) eye left 49.9% or 579 eyes right 50.1% or 581 eyes pre SR equiv: mean D ± 2.58 D (from to 6.38) pre SR sph: mean D ± 2.66 D (from to 7.00) pre SR cyl: mean D ± 1.01 D (from to 0.00) number of eyes 1 m: 848 (follow up rate 73.1%) post SR equiv: mean D ± 0.44 D (from to 1.63) post SR sph: mean D ± 0.45 D (from to 2.25) post SR cyl: mean D ± 0.36 D (from to 0.00)

9 All LASEK cases efficacy after 1 and 4 months

10 Audits Custom LASEK Myopes

11 Audits: Custom LASIK Myopes

12 Complications Undercorrection (+/- 1D) or overcorrection of refractive error require enhancement – lasek enhancement rate of 4% - high refractive errors more likelyUndercorrection (+/- 1D) or overcorrection of refractive error require enhancement – lasek enhancement rate of 4% - high refractive errors more likely Lasik flap complications (decentered, thin) 6 eyes require additional enhancementLasik flap complications (decentered, thin) 6 eyes require additional enhancement Epithelial ingrowth requiring flap lift and debridement 4 eyesEpithelial ingrowth requiring flap lift and debridement 4 eyes 2 eyes lost one line of best corrected acuity2 eyes lost one line of best corrected acuity 14 eyes gained one or more lines of best acuity14 eyes gained one or more lines of best acuity
