KeraSoft
Of course there are many, usually more extreme cases where off the shelf disposable lenses do not work. That’s where the KeraSoft IC comes in. My fitting set, the only one in NZ as far as I know, arrived early in the New Year. Since my return from travels in February I have now trialed and fitted a few complex cases with some great results. 

Challenging Cases
It’s never fair to a new lens design to throw all the grief cases at it that have been building up on ones desk for the past six months. Such cases have generally failed outright or failed to obtain decent wearing time, comfort, vision or physiology. Trialing a new lens on such cases will likely increase the failure rate. I am pleased to report that of the trials I did the success rates with KeraSoft IC were pretty impressive. Two cases have decided to think about it and one simply had too poor vision to benefit. Such cases are really at the graft stage as RGPs, piggybacks, semi-sclerals and other options have failed to date. I currently have three cases that are all doing rather well.

In general I have been suitably impressed with the lenses and in particular the stability and accuracy of fit and lack of rotation, particularly considering the complexity of the lenses and corneas involved.
My results with a variety of NZ, AUS and UK manufactured custom silicone hydrogel torics in high powers over the past few years have been an almost universal disappointment. The KeraSoft results were thus a pleasant surprise.

As usual I temper my comments with the fact that these are initial results but the true test is time.
