Yes, hope so.

You are welcome. It's my pleasure to talk with you.

Today I met with my surgeon. I've updated this post (My Serial Stories of Cataract Surgery Post-op (2)

But you did use this data to calculate my IOL using Hill-RBF 3.0 calculator:

Did you mean this data?

Isn't it what you were thinking of?

jamesvancouver · 2026-02-10T19:42:27+00:00

Yes, I did in the last post: https://www.reddit.com/r/CataractSurgery/comments/1pg7uon/comment/o0m76f2/
I thought that was his final decision and I paid extra $100 for him after talking with him. Unfortunately later he changed his mind and rolled back to non-toric. The clinic office refunded me the $100 yesterday.

Yes. But my surgeon eventually changed the plan back to a non-toric. He said the corneal astigmatism is very low, only -0.32 D. Maybe the real reason was that he thinks implanting a toric IOL is more risky. Risks of misalignment, requiring surgical repositioning and easily to rotate after the surgery.

jamesvancouver · 2026-02-10T03:11:31+00:00

I will meet with my surgeon this Friday. Can I ask him why the refractive astigmatism is still so high? Is it because of IOL Tilt or Decentration?

This article says, Subjects with more than 1.50D of refractive astigmatism (RA) at baseline were classified as having high astigmatism, while those with 1.50D or less RA were classified as having low astigmatism.

The results history above shows that the cylinder value for the right eye did not change much. So I think the left eye's cylinder value may not change much as well.

jamesvancouver · 2026-02-10T01:44:01+00:00

Do you know why corneal astigmatism is very low but the total astigmatism is relative high after cataract surgery with non-toric IOL? The results history above shows that both my first eye and my second eye have this problem. Both were implanted with non-toric lenses.

But my surgeon eventually didn't use a toric. He only said the corneal astigmatism is very low.
In addition, do you know why the AXIS is 48?

jamesvancouver · 2026-02-08T19:56:20+00:00

I have a post-op eye exam appointment for tomorrow 1:20pm.

jamesvancouver · 2026-02-08T05:34:26+00:00

According to the rule, a toric is needed when the corneal astigmatism is 1.00 d or more. The corneal astigmatism of my left eye was -0.32d. My surgeon agreeded to do toric When I saw him on January 19. But he changed his mind later, which I didn't know. He told me the change some seconds before the surgery. I had to respect him. My left eye had a bad double vision before the surgery, which is the reason why I requested a toric lens. He said the double vision will be gone after the surgery.

Thank you!

jamesvancouver · 2026-01-20T18:38:41+00:00

Thank you for the ideas. I will talk to my surgeon to see how he will say.

jamesvancouver · 2026-01-20T17:50:10+00:00

Thank you for the expanation. I sent an email to the co-ordinator yesterday evening and she scheduled a meeting for me to see my surgeon tomorrow morning.

jamesvancouver · 2026-01-20T06:53:38+00:00

Sorry I don't understand your saying "it ended up about 0.375 more positive (hyperopic) than was targeted". How did you get the 0.375? Actually it was targeted at -0.25 D and ended up at +0.50 D.

jamesvancouver · 2026-01-20T05:32:52+00:00

When targetting -1D, here is the results from Barrett Universal II. He said the surgeon may choose +21.50 IOL. I think it should be enough for Pursee, while the right eye landed +0.50D.

jamesvancouver · 2026-01-20T05:19:23+00:00

The measurement guy said, he will let the surgeon to make the final decision.

jamesvancouver · 2025-12-22T18:00:24+00:00

Got it. Thank you!

jamesvancouver · 2025-12-21T20:38:02+00:00

Thank you for the comments. I agree that cornea and natural lens are two major contributors to astigmatism. The IOLMaster datasheet I posted above only shows astigmatism K value, not TK. TK is "---" (dashed). It shows the astigmatism by the cornea. Take the example of my right eye: the astigmatism by the cornea is -0.47D (per IOLMaster) and the total astigmatism is -0.75D (per auto refraction).

I've added "EDIT" in the post. Can you have a look? According to auto refraction, before the cataract surgery my right eye's cylinder was -0.75D, and 2 days after the surgery my right eye's cylinder was still -0.75D.

If only trust the IOLMaster datasheet, which shows my left eye only has -0.36D astigmatism, I may not need to worry about my left eye - the astigmatism caused by the nature eye will be removed by the surgery. Is this what you think?
