## Most critical reviews (4 lowest-rated)

### 1/5 — Problem with ios 11

*2018-01-06*

It doesn’t work in IOS 11

### 4/5 — Add two boxes to enter K’s

*2018-03-24*

This is a useful app.  My one suggestion would be to make two boxes to enter the steep K and the flat K.  This would be a very simple programming step and would save the user from having to average the two K’s each time.

### 4/5 — A solid app

*2012-02-10*

A definitely handy must-have for cataract surgeons.  A table with a constants for common IOLs would be a nice addition to the program.

### 5/5 — Great app

*2021-09-14*

I use this for phaco cases that require intra-op measurements. Easy to use. I’ve used this for 2 years, so far no problems.
