An interventional study of Sutureless Intrascleral Intraocular Lens Fixation and Modified Iris Cerclage Pupilloplasty in Aphakia and Mydriasis, sponsored by Changzhou Second People's Hospital affiliated with Nanjing Medical University. Recruiting at 1 site in China. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2023-04-25.
Sponsored by Changzhou Second People's Hospital affiliated with Nanjing Medical University · Not applicable, Interventional, and Treatment
In this study, patients with various causes of pupillary dilatation were recruited, and medical records and ophthalmology examinations, including slit-lamp examination, visual acuity, best corrected visual acuity, intraocular pressure, pupil diameter, corneal endothelial cell count, fundus examination, and photophobia score, were collected. Those who met the recruitment criteria underwent modified iris cerclage pupilloplasty. The modified iris cerclage pupilloplasty was performed by making four clear corneal incisions, suturing the iris 3-4 times consecutively between each two incisions, completing 360 degrees of iris suturing in sequence, and finally tying the knot intraocularly to complete the iris cerclage.
69 studies on the registry are indexed under Aphakia; 6 are open to participants now.
This study's planned enrollment of 20 is below the median of 103 across 52 interventional studies indexed under Aphakia.

Procedure: Sutureless Intrascleral Intraocular Lens Fixation and Modified Iris Cerclage Pupilloplasty
In this study, patients with various causes of pupillary dilatation were recruited, and medical records and ophthalmology examinations, including slit-lamp examination, visual acuity, corrected visual acuity, intraocular pressure, pupil diameter, pupil area, corneal endothelial cell count fundus examination, and photophobia score, were collected. Those who met the recruitment criteria underwent modified iris cerclage. The modified iris cerclage was performed by making four clear corneal incisions, suturing the iris 3-4 times consecutively between each two incisions, completing 360 degrees of iris suturing in sequence, and finally tying the knot intraocularly to complete the iris cerclage.
