The impact of speculum uses on the incidence of blepharoptosis in patients undergoing phacoemulsification surgery: A prospective analysis.
Observational study in Indian journal of ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThe primary objective of this study was to investigate the possible role and assess the potential relationship of speculum use during phacoemulsification surgery in the occurrence of blepharoptosis.
methodsOur study is a prospective observational design to analyze patients who underwent phacoemulsification surgery under topical anesthesia between October 2017 and May 2018 at a tertiary eye hospital in South India. All patients had their Margin Reflex Distance 1 (MRD1), levator palpebrae superioris (LPS) function, and lid crease distance (LCD) measured before and after surgery on day one, one month, three months, and six months to evaluate the extent of ptosis at each time point that was recorded clinically and photographic documentation for accurate evaluation.
resultsOut of the 221 patients who participated in the study, a total of 250 eyes were examined. On postoperative day one, 34 patients (15.8% with a rigid speculum and 11.4% with a non-rigid speculum) developed ptosis. At the one-month follow-up, ptosis persisted in four patients, with one patient having undergone surgery using a rigid speculum and the rest of three patients with a non-rigid speculum. However, further follow-ups at three and six months revealed a complete resolution of ptosis in all cases, indicating that the ptosis was transient and resolved spontaneously.
conclusionSpeculum use cannot be considered as the sole causative factor for postoperative ptosis, as a multitude of other modifiable factors, such as superior rectus bridle suturing, anesthetic approach, prolonged patching, and duration of surgery, may have an additive effect alongside speculum used in the development of postoperative ptosis.
