Sulcus IOL calculator by MIOLO
Sulcus IOL power after posterior capsule rupture
Axial length refines the eye model and the short-eye alert
About MIOLO Sulcus
MIOLO Sulcus is a free calculator that converts the planned capsular bag IOL power into the power of a three-piece lens in the ciliary sulcus after posterior capsule rupture.
What it is for
When the capsular bag can no longer hold the planned lens, it gives the power for a three-piece intraocular lens placed in the ciliary sulcus, with or without optic capture in the rhexis.
Who it is for and when to use it
It is built for cataract surgeons facing a posterior capsule rupture who already have the IOL power calculated for the capsular bag.
What you enter
The bag-calculated IOL power and the A-constant of the planned lens from the original biometry report, the three-piece lens to be implanted (choosing one fills its A-constant, which stays editable), whether the optic is captured in the rhexis, and, optionally, the axial length (AL).
What you get
The sulcus IOL power, a table of sulcus power options, clinical guidance, and, for signed-in surgeons, the option to save the case.
Frequently asked questions
- Is it free?
- Yes. The calculator is free to use, with no fees and no ads.
- Do I need a new biometry?
- No. It starts from the power already calculated for the capsular bag and the A-constant of that lens, both found on the original biometry report.
- What changes with optic capture?
- With the optic captured in the rhexis, only the A-constant conversion applies, with no further power reduction.
- Why enter the axial length if it is optional?
- It refines the eye model and enables the short eye alert.
- Does it work on mobile?
- Yes. The page adapts to phones and tablets, and the result reads the same as on a desktop.
