In the standard treatment group (laser iridotomy), can we do lens extraction if the angle does not open after laser treatment?
No. Lens extraction in the standard care group may only be done after PI and medical treatment fail to control the IOP. In other words, surgery (lens extraction) may not be done if IOP appears to be well controlled with laser and meds even if the angle remains closed. The concept of maximum medical treatment is a pragmatic one, but the indication for surgery would be guided by IOP, not by the angle appearance.
