Dr Oyakawa,
I met my cataract surgeon 2nd time to discuss the option of Toric lens. The doctor spent more than 1/2 hr and patiently explain to me if the problem is in the corneal, he should fix it in the corneal unless it is really necessary.
He told me that part of the 1.75D astigmatism I have is lenticular (about 0.5D, the exact number will be known after the IOL master measurement) and which will be gone when the lens is removed. With the placement of the incision for IOL, he can correct another 0.5D.
He also tends to under-correct than over-correct the astigmatism and he think I have less than 0.75D astigmatism left to be corrected by the LRI. He told me that he CANNOT agree to implant an toric lens in my scenario.
He thinks that he only needs a very small LRI (around 3mm) to correct such a small amount of astigmatism. The healing time will be short.
In some of your early posting you mentioned that the dry eye induced by LRI should recover in 3 to 6 months and this number really give me a concern. Does the healing time related to the length of the incision ? If the LRI incision is very small, will the healing time less than 3 months ? I heard that LRI incision depth is 0.6mm, how much is it compared to the incision done by the incision for the IOL ?
Finally, how common people's astigmatism is lenticular ?
Thanks a lot
Dr.O.
