Purpose
To study the long term effect of femtosecond laser assisted corneal arcuate incision on the post operative astigmatism and final visual outcome.
Setting
Bejan Singh Eye Hospital , Nagercoil, India
Methods
Inclusion criteria:
immature cataract
patients with minimum one year followup
astigmatism of 1D or less
patients who underwent FLACS with arcuate incision
Exclusion Criteria:
more than 1D astigmatism
mature cataract
other ocular pathologies
Method
50 eyes of patients who underwent FLACS with corneal arcuate incision for less than 1D astigmatism and had a minimum of 1 year followup were selected retrospectively. Preoperative Uncorrected visual acuity, best corrected visual acuity( Snellens visual acuity chart), optical biometry (IOL master 700) and VERION were taken into account.
Post operative 1 month and 1 year uncorrected visual acuity, best corrected visual acuity and refraction were noted.
Results
The mean visual acuity at post Op 1 month was 6/6(0.8). The mean visual acuity at 1 year post op was 6/6( 0.9).There was no statistically significant difference.
The mean astigmatism at 1 month follow up was 0.19D with SD 0.38 and the mean astigmatism at 1 year follow up was 0.18 with SD 0.33. The1 month and 1 year change in astigmatism was not statistically significant.
For less than 1D astigmatism and patients not willing for toric IOL, Femto assisted corneal arcuate incision can be used.
Conclusions
It can be concluded that femtosecond laser assisted corneal incision can be used to correct low astigmatism and the results are long standing.
It can be used as alternative to toric IOL in low astigmatism.
