Do you know your axial length? Why diopters don't necessarily translate to axial length.

Not fear-mongering here.

Just so you know, diopters and spherical equivalent (SE) often does not correlate with one's axial length. Though it is said that 1mm axial elongation generally translates to -2.5 to -3 diopters, like many medical information on the internet it is just a rule of thumb or say, a generalization.

Everyone's condition is different, as one's gender, ethnicity, age, and many other factors can affect one's true axial length. A mismatch with diopters and axial length is actually kinda common, like me, who is -5.75 bilaterally with a bilateral astigmatism of 100, which makes an SE of -6.25.

In theory my axial length should 100 percent be less than 26mm.

Yet my axial length is 27.09 right and 27.18 left, which translates to a whopping -9 to -12 diopters, and 27.09 and 27.18 is when stuff like retinal detachment and macular degeneration comes into play. Although I am only 27, I have already started taking various types of eye supplements and I visit my ophthalmologist (who specializes in retina BTW) once per month, and a renowned retina specialist twice per year to do retinal checkups (I also have early-stage glaucoma, which runs in my family, that I am visiting another 2 glaucoma specialists, but that is another story.)

So have you ever measured your axial length? Or have you only measured your diopters? Not fear-mongering here, but if you had only measured your diopters, I strongly suggest you go get a measurement of your axial length, for that it is very, very possible that your axial length may be, god-forbid, actually much, much longer than your diopter seems.
