“…This study was carried out to correct the iris defects by using SFTP, and the results were compared among congenital and traumatic iris defects. Iris defects in the past have been repaired using various techniques of pupilloplasty such as Mc Cannel suture,[ 6 7 8 ] modified Siepser knot,[ 9 10 ] iris cerclage,[ 11 12 ] iris mattress suture,[ 13 ] sewing machine technique,[ 14 ] and iris cautery.

Purpose: To compare postoperative cosmesis, mydriasis, fundus visibility, and anterior chamber depth (ACD) in congenital and traumatic iris defects after single-pass four-throw pupilloplasty (SFTP). Settings and Design: Hospital-based non-randomized interventional study. Methods: SFTP was done along with phacoemulsification in six patients each with congenital and traumatic iris defects, and the patients were followed for a minimum period of 3 months. The postoperative pupil shape, size, mydriasis, and ACD were compared between the two groups. Results: Tissue approximation was successful in 11 out of 12 patients (91.7%), whereas it failed to do so in one patient with traumatic iris tear (8.3%). A central round pupil was attained in all six patients with congenital defects (group 1), whereas in the traumatic group (group 2), a central round pupil was attained in four cases. Group 1 did not show a significant reduction in horizontal pupil diameter, but group 2 had a significant reduction in pupil diameter postoperatively. Mydriasis and fundus visibility were satisfactory in all cases. There was a significant deepening of ACD in both groups. Conclusion: Traumatic mydriasis usually requires SFTP at two opposite poles to achieve a central pupil with a significant reduction in pupil size, whereas congenital coloboma requires SFTP to be done at the site of coloboma with occasional enlargement at the opposite pole if the pupil is eccentric.

“…Numerous iris suturing techniques and pupil reconstruction procedures have been practiced in ophthalmology for more than four decades. [1234567891011] The indications varied widely including congenital iris deformities, traumatic iris tear or dialysis, and pupil abnormalities due to surgery. Other than regular pupilloplasty procedures, few other indications have been introduced in recent years.…”

“…There are several iris repair techniques reported in the literature which are performed for iris coloboma, iris trauma, iridodialysis, and iatrogenic iris tear. [1234567891011] However, there are no reports concerning the assessment of post surgical configuration changes in such eyes. Moreover, the intraocular polypropylene or prolene suture, which is commonly used in iris repair, has also not been widely studied after pupilloplasty.…”

Purpose: To analyze the morphological changes in the iris-knot complex configuration using spectral-domain optical coherence tomography (SD-OCT) following the single pass four throw (SFT) pupilloplasty. Methods: In this retrospective case series, eyes with SFT pupilloplasty were examined by SD-OCT (Optovue). Iris morphology compared to the normal iris, presence of specific patterns (single hump, double humps, peaks and valleys, tethering), prolene suture, knot complex (length and orientation), and intraocular lens (IOL) vault were evaluated. Results: Overall, 41 knots of 26 patients with a mean time duration of 3.1 ± 2 months from surgery were analyzed. Iris configurations seen were single hump ( n = 28, 63.8%), double humps ( n = 7, 17%), loop ( n = 2, 4.8%), flat ( n = 3, 7.3%), and mulberry ( n = 1, 2.4%). The mean length and the height of the knot complex was 784.1 ± 433.7 μm and 317.7 ± 110.4 μm, respectively. Knot positions were at 3 clock hours in 9 eyes (21.9%), 9 in 8 eyes (19.5%), and others in 24 eyes (58.5%). Cut end of the prolene suture was detectable in 26 eyes (63.4%) as hyper-reflective line, and the mean cut length was 465.8 ± 321.1 μm. The suture was predominantly vertically oriented (80.6%) to the iris with a mean distance of 3.6 ± 0.3 mm (2.6–4 mm) away from corneal endothelium. The mean distance from the knot complex and the IOL was 289.2 ± 146 μm and the mean anterior chamber depth was 4.1 ± 0.1 mm. Conclusion: A significant change in iris configuration was noted after SFT pupilloplasty, and vertically oriented retained prolene suture was predominant with good endothelial vault.
