The nature of the residual refraction was explained for preferential power modification of a toric lens
that compensates vision in the spectacle or the corneal plane.
“The TRULIGN Toric lens
both reduces the negative impact of pre-existing astigmatism on postoperative vision and also imparts excellent distance and intermediate vision and functional near vision, all through a single surgical procedure,” said Dr.
CVI's extensive range of toric lens
parameters offers practitioners the widest choice of fitting alternatives in the industry.
The TCA is overestimated in WTR eyes (0.5 to 0.6 D) and underestimated in ATR eyes (0.2 to 0.3 D) when planning toric lens
implantation without considering the PCA .
business, which includes annual replacement products as well as disposable-planned replacement brands, grew 23% during the second quarter.
Although they reported no significant change in the corneal curvature after 3 months discontinuation of lens wear as compared to baseline, they did not compare between spherical lens design and toric lens
However, generally, for low astigmats, a toric lens
will provide superior vision to an aspheric lens alone.
Safilens will be launching its new daily toric lens
at the BCLA Conference and Exhibition.
(3) Toric lens
design has also advanced to provide greater fitting stability.
