Successful integration of modern multifocal
IOLs into a clinical practice
Lim SJ

Presbyopia rehabilitation becomes more important in cataract operation
nowadays. For this, new generation of multifocal lens shows
very successful clinical outcome so far. For successful integration of
modern multifocal IOLs into a clinical practice, the importance of
patient selection and accurate biometry including astigmatism control
cannot be overemphasized. Additionally, posterior capsule opacification
is absolutely critical obstacles in multifocal IOLs especially
for near vision. In our study for 3 years follow up of 500 cases of
Array (former zonal refractive type silicone IOLs) lenses, average
uncorrected visual acuity were measured 0.81 at far and 0.64 at near
immediate postoperatively. However, average uncorrected visual
acuity decreased 0.60 at far and 0.34 at near at 3 years after operation.
In our another study for the clinical effect of the planned posterior
capsulorhexis with Array IOLs implantation, average uncorrected
visual acuity were measured 0.73 at far and 0.54 at near at
3 years after operation. These results show the importance of posterior
capsular opacification for the full function of multifocal IOLs,
especially for near vision. In contrast, our recent study for clinical
outcome of Restor lenses (Apodized diffractive acrylate IOLs) for 1
year follow up shows very much desirable result compare to former
Array IOLs. We performed patient selection very cautiously and
more accurate biometry was performed using standard A scan and
IOL master simultaneously. And we need perfect capsulorhexis to
reduce the developing of posterior capsular opacification, especially
fibrotic type. For this, anterior capsule must overlap 360 degrees of
IOL optic margin and there must be no optic capturing by capsulorhexis.
This perfect capsulorhexis can give us not only less developing
of posterior capsular opacification but also less tilting and decentration
of multifocal IOL.
