Why reposition and suture instead of replace
Replacement with large one piece PMMA sclerally sutured IOL» Requires large incision» Long healing time and visual recovery
– In older patients may be very significant time
Replacement with AC IOL» Longer healing time

Why iridoplasty?
Better optics and less glare Less peripheral anterior Synecheia
» Less decrease in outflow Better tolerance of mild lens
decentration

Corneal edema Cystoid macular edema
Recurrence of dislocations

Dislocated IOLs
A problem? YES When to treat:
» Prevention: larger capsulotomies,– Capsular tension rings?
» When lens causing symptoms or likely to sublux Surgical options With appropriate repair outcomes are excellent and recurrences
are rare The least invasive procedure is the best, iris suturing leads to
consistent excellent results
