M-flex T Demonstrates Predictable Astigmatic Correction
Posted on 06/10/2014
The October 2014 Issue of the Journal of Cataract & Refractive Surgery (JCRS) presents a paper by Mr Vinod Gangwani, MRCOphth, FRCS, using the M-flex T and M-flex with Peripheral Corneal Relaxing Incisions (PCRIs) to correct astigmatism in patients requiring multi-focality.
This randomised, single blind study included patients with bilateral corneal astigmatism of between 1.0 and 2.5 Diopters and demonstrated the advantages of toric IOLs over PCRIs.
In the analysis of 58 eyes with 29 patients, the mean residual refractive astigmatism 3 months after surgery was 0.45 ± 0.49 D (maximum 1.50 D) in the toric IOL group and 0.72 ± 0.61 D (maximum 2.00 D) in the PCRI group with the difference being statistically significant (p = 0.46). This reduction was echoed in objective measures with a mean absolute vector difference of 1.76 ± 0.47 D in the toric IOL group and 1.56 ± 0.63 D in the PCRI group, again this difference was statistically significant (p = 0.042)
The rotational stability of the toric lens platform was further established with mean absolute misalignment of the M-flex T from the intended position 3-months postoperatively at 2.52 ± 1.97 degrees.
