LaserVision Refractive Audit

Mr John Fenton FRCSI


Refractive audit

Refractive audit

1160 consecutive procedures in 14 months

300 lasek

816 lasik

85 % choose wavefront guided treatment (of benefit if high refractive errors ,night glare, astigmatism, large pupils) –15% standard treatment – equal outcomes for low errors

Post-op 96% binocular distance acuity

<= 6/6 unaided

Laservision refractive audit

number of eyes pre OP: 1160

[email protected] average 35 years (from 18 to 66)

eye left 49.9% or 579 eyes

right 50.1% or 581 eyes

pre SR equiv: mean -2.53 D ± 2.58 D (from -9.50 to 6.38)

pre SR sph: mean -2.11 D ± 2.66 D (from -9.25 to 7.00)

pre SR cyl: mean -0.86 D ± 1.01 D (from -7.25 to 0.00)

number of eyes 1 m: 848 (follow up rate 73.1%)

post SR equiv: mean -0.21 D ± 0.44 D (from -2.50 to 1.63)

post SR sph: mean -0.10 D ± 0.45 D (from -2.50 to 2.25)

post SR cyl: mean -0.22 D ± 0.36 D (from -2.75 to 0.00)


All lasek cases efficacy after 1 and 4 months

All LASEK cases efficacy after 1 and 4 months

Complications

Complications

Undercorrection (+/- 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 enhancement

Epithelial ingrowth requiring flap lift and debridement 4 eyes

2 eyes lost one line of best corrected acuity

14 eyes gained one or more lines of best acuity
