I informed my doctors that, in many cases, the positioning of the hole is temporal, as you mentioned. However, right after that, she informed me that it would be very bad. During my next visit, I plan to ask her why. Many specialists even advise selecting the right position based on individual anatomy, preferably at the 3 and 9 temporal positions, as far away from the eyelids as possible (source: MD Roundtable: Iridotomy Decisions for the Narrow Angle.) Dr. Asrani's last comment supports the same viewpoint.

I was surprised when my doctor had never heard of such a side effect. Nonetheless, after conducting a comprehensive online search, it seemed that the McCannel structure could be a solution for me (source: McCannel Suture Technique Resolves Persistent Dysphotopsia Following Laser Peripheral Iridotomy in Phakic Eyes). However I don't have Phakic Eyes but these patients have their original lenses just I have.

My doctor informed me that she sutures the iris quite frequently. In my case, there are two options. One involves potential damage to my lenses from the suturing process, necessitating the replacement of my original lenses with intraocular lenses (artificial). (I am too young for this)The other option may involve reaching the hole from the outside, but this is considered very challenging. Since the McCannel suture is a US invention, it is more likely available there than here. Many doctors refer to this technique in cases similar to mine. I also came across an individual whose hole was successfully sutured; however, it didn't help much because his eyes were blue. Fortunately, I have brown eyes.

On a side note, my glaucoma was well-treated with two types of eyedrops. In 2022, my eyes were dilated, and nothing went wrong. However, I underwent two laser procedures since then to eliminate the need for any eye drops. The first procedure, SLT, was successful, allowing me to discontinue one eye drop. The second, femtosecond laser trabeculectomy, is still in the research phase and is only available in my country. God knows but may be these procedures affected my angles. The first was successful, but the second had no beneficial effect. I was told that I was the 1 in 1000 case where the procedure did not work as expected. 🙁

I am not in a rush as some doctor advice it would be better and it resolves on there own. However based on the comments on internet I am very sceptical. Of course I will try more contact lenses and see how improve my quality of my life.

Anyway, I really appreciate your effort to convey my message to your GS. Let's see if she has any suggestion.

I read every article imaginable before I decided not to have the iridotomy, but yours was an emergency unfortunately.
I looked on Youtube and found the procedure being done by a Dr. Rami Shasha, a renowned Ophthalmologist. He seems to work in the US and Canada. I looked to see where he worked, but could not find a specific hospital.
I checked Linkedin and found him.

Perhaps you can contact him and find out if he still does the procedure and where?
Here is the contact number from Linkedin.

You'll have to get on Linkedin, to contact him

Please let me know if you can find out where he does the McCannel Suture technique.
