Objective: To investigate the clinical outcomes of three surgical approaches for ectopia lentis in Marfan syndrome (MS) patients who had undergone crystalline lens removal with posterior chamber intraocular lens (IOL) implantation techniques comprising the intrascleral fixation of IOL, sutured scleral fixation of IOL, and IOL implantation with the use of a Cionni capsular tension ring (CTR). Methods: This is a retrospective comparative study, including 35 eyes of 21 patients who underwent the intrascleral fixation of IOL (group 1), scleral IOL fixation with the Z-suture (group 2), and IOL implantation with the use of a Cionni CTR (group 3) following crystalline lens removal. The surgical indications were as follows: no improvement in visual function after eyeglasses or contact lens application due to excessive irregular astigmatism and advanced crystalline lens decentration in which the edge of the crystalline lens came up to the optical axis, or dislocation of the crystalline lens resulting in aphakia and secondary glaucoma due to lens dislocation. The surgical outcomes and complications due to surgery were compared between the groups. Results: The mean age of the patients in the study was 12.3 ± 8.7 years (5–32 years). There were 10 eyes in group 1, 13 eyes in group 2, and 12 eyes in group 3. Visual acuity improved significantly in each group after surgery. Ocular residual astigmatism did not differ significantly between the groups ( p = 0.51). Conclusion: There were no significant differences between the three surgical approaches in the current study in terms of the postoperative results and complications.

Background and objectives: To evaluate anterior capsule opening (ACO) contraction and late intraocular lens (IOL) dislocation after cataract surgery in patients with weak or partially absent zonular support and assess methods of reducing these complications. Materials and methods: For this prospective study, we enlisted cataract surgery patients in our hospital with preoperative diagnoses of weak zonules. All patients received phacoemulsification surgery with implantation of a hydrophobic acrylic IOL and capsular tension ring (CTR). ACO reductions were measured for six months after enrolment. Data on late IOL dislocations were collected five years after enrolment of the last patient. Results: Fifty-three patients were enrolled from 2011 to 2015. Over the six-month active follow-up period, ACO area reduction was 23% in patients receiving CTRs of 11 mm diameter and 8% for patients with CTRs of 12 mm, with an overall mean of 15% reduction. Five years after the last patient was enrolled, seven patients (13%) had experienced late IOL-CTR-capsular bag dislocation. For these patients, the mean ACO reduction in the first six months of follow-up was 33%, including for those who had received neodymium-doped yttrium aluminum garnet (Nd: YAG) anterior capsulotomies. Conclusion: Use of hydrophobic acrylic lenses and CTR reduces ACO contraction, with rates comparable to those after cataract surgery without ocular comorbidity. Our patients experienced a relatively high rate of late IOL-CTR-capsular bag dislocation. However, dislocated complexes were easily repositioned and few patients required IOL exchange. Frequent visits are warranted to promptly detect late complications of cataract surgery in patients with weak zonular support.

Abstract OBJECTIVE To compare 3 anal purse-string suture techniques for resistance to leakage and to identify the suture technique requiring the fewest tissue bites to create a consistent leak-proof orifice closure. ANIMALS 18 large-breed canine cadavers. PROCEDURES 3 purse-string suture techniques (3 bites with 0.5 cm between bites [technique A], 5 bites with 0.5 cm between bites [technique B], and 3 bites with 1.0 cm between bites [technique C]) were evaluated. Each technique involved 2-0 monofilament nylon suture that was placed in the cutaneous tissue around the anus and knotted with 6 square throws. Standardized 2.0-cm-diameter circular templates with the designated bite number and spacing indicated were used for suture placement. Leak-pressure testing was performed, and the pressure at which saline was first observed leaking from the anus was recorded. The median and interquartile (25th to 75th percentile) range (IQR) were compared among 3 techniques. RESULTS Median leak pressure for technique A (101 mm Hg; IQR, 35 to 131.3 mm Hg) was significantly greater than that for technique C (19 mm Hg; IQR, 14.3 to 25.3 mm Hg). Median pressure did not differ between techniques A and B (50 mm Hg; IQR, 32.5 to 65 mm Hg) or between techniques B and C. CLINICAL RELEVANCE Placement of an anal purse-string suture prevented leakage at physiologic colonic and rectal pressures, regardless of technique. Placement of 3 bites 0.5 cm apart (technique A) is recommended because it used the fewest number of bites and had the highest resistance to leakage.

A New Technique

Forefoot and lesser digital pathology continues to be a challenging area of surgical correction for foot and ankle surgeons. Many techniques for the correction of digital deformities secondary to plantar plate rupture, regardless of planal dominance, have been described including direct repair and metatarsal shortening osteotomies for repair. The authors present a new technique for multiplanar correction of deformed lesser digits without direct repair of the plantar plate rupture utilizing a specialty suture. The technique utilizes a braided synthetic polyethylene Nylon suture, which has been traditionally used for open or arthroscopic shoulder labrum repair, for the stabilization of the lesser metatarsophalangeal joint. This novel technique guide for the correction of transverse and sagittal plane deformities of the digit at the metatarsophalangeal joint negates the need for a plantar incisional approach for plantar plate repair or metatarsal head osteotomy from a dorsal approach with augmented stabilization.
