Implication

Supports PAM prediction in confirmed ARMD; leaves open accuracy in doubtful cases and needs prospective validation.

Structured PICO

Does the Potential Acuity Meter accurately predict postoperative visual acuity in patients with cataract and age-related macular degeneration?

P
Population
130 cases of cataract, 54 of whom had preoperatively proved or suspected age-related macular degeneration (ARMD) associated with a cataract.
I
Intervention
Preoperative evaluation with Potential Acuity Meter (PAM) followed by extracapsular extraction and intraocular lens (IOL) implantation
C
Comparator
Final visual acuity at 3 months postoperatively (diagnostic accuracy comparison)
O
Outcome
Accuracy and specificity of PAM prediction compared to final visual acuity at 3 months postoperativelysurrogate

The Potential Acuity Meter is a reliable clinical technique for predicting visual results after cataract surgery in patients with confirmed or doubtful macular pathology.
