Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.
Questions and results
Phacoemulsification compared with laser peripheral iridotomy for acute primary angle closure
Population: Participants with acute primary angle closure after initial medical treatment to lower intraocular pressure
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Proportion of participants with IOP control (higher number of events is better) Phacoemulsification vs laser peripheral iridotomy | RR 1.66 [1.28, 2.15] | 2 studies · 97 participants | Low Downgraded: risk of bias, inconsistency |
Proportion of participants requiring further IOP‐lowering interventions (additional surgery, medications, or both) (lower number of events is better) Phacoemulsification vs laser peripheral iridotomy | RR 0.07 [0.01, 0.51] | 2 studies · 99 participants | Very low Downgraded: risk of bias, imprecision |
Proportion of participants with 1 or more recurrent APAC episodes in the same eye (lower number of events is better) Phacoemulsification vs laser peripheral iridotomy | RR 0.32 [0.01, 7.3] | 1 study · 37 participants | Very low Downgraded: risk of bias, imprecision |
Mean number of IOP‐lowering medications required (lower number of medications is better) Phacoemulsification vs laser peripheral iridotomy | no estimate extracted | 1 study · 60 participants | Low Downgraded: risk of bias, imprecision |
Mean IOP, measured by any method (mmHg) (lower IOP is better) Phacoemulsification vs laser peripheral iridotomy | no estimate extracted | 1 study · 62 participants | Low Downgraded: risk of bias, imprecision |
Mean change in angle findings, measured by any method Phacoemulsification vs laser peripheral iridotomy | no estimate extracted | 2 studies · 94 participants | Very low Downgraded: risk of bias, inconsistency |
Adverse effects Phacoemulsification vs laser peripheral iridotomy | no estimate extracted | 2 studies · 99 participants | Low Downgraded: risk of bias, imprecision |
