Autologous blood-assisted scleral fixation of intraocular lens.

ABSTRACT: In this technique, the lamellar scleral tunnel is fashioned to cover IOL haptics and autologous blood is used to close the conjunctiva, which alleviates the need for fibrin glue. The cornea is marked at four and 10'O clock meridian, and 2 mm incision is made on the conjunctiva. A lamellar scleral tunnel is fashioned 2 mm superior on one side and 2 mm inferior on the other side of this mark. The IOL is inserted into the anterior chamber and the haptics are exteriorized using bent 26-gauge hypodermic needle, flanged, and buried in the tunnel. A visible conjunctival blood vessel is punctured, allowing the blood to pool underneath the conjunctiva. The conjunctiva is approximated with the help of blood coagulum and allowed to remain dry for 3 min. Lamellar scleral tunnels give adequate cover to haptics, and autologous blood can be used to glue the conjunctival flaps instead of fibrin glue.

In-and-out technique for intraocular lens scleral fixation.

Project description:We describe a modified scleral fixation method to facilitate the good centration and adequate tension of sutures at both ends with addition of an internal fixation knot that reduces decentering of the IOL in a patient with postsurgical aphakia. Using an ab externo suture technique to fixate the haptics to the scleral wall, an additional loop knot is tied 1 mm next to the fixation knot at the haptic. In the technique, an internalized suture and an additional suture knot is tied while holding it close to the fixation knot at the haptic using a needle holder or McPherson forceps. The externalized sutures are secured by taking a bite of transclera and tying the suture to itself. This technique is simple and easy, and adds an internal check valve to prevent excessive pull and decentering of the intraocular lens at one side. The internal check valve also serves as a criterion for the point of fixation at each end.

Scleral fixation of one piece intraocular lens by injector implantation.

Project description:Aim of studyWith an ab-interno technique of transscleral suturing of current one-piece posterior chamber intraocular lenses (PC IOLs) by injector implantation in the absence of capsular support, we aimed to demonstrate the possibility of the implantation of one-piece acrylic PC IOLs that might be produced in the future for only scleral fixation through small clear corneal incision.Materials and methodsCase report and literature review.ResultsThis procedure has been performed in eight aphakic eyes with four different types of IOLs. Good centration was achieved with minimal technical effort. All patients had well-centered and stable lenses postoperatively during 9-18 months follow-up.ConclusionWe managed to decrease the risks of surgical trauma and intricate surgical maneuvers requirement. With this technique, excessive fluid leakage and consecutive hypotony can be minimized.

Cable tie technique for securing scleral fixation suture to intraocular lens.

Project description:PurposeTo report a new flanged intrascleral fixation technique for subluxated or dislocated intraocular lens (IOL) with c-loop or double c-loop haptics (cable tie fixation method).ObservationsWe introduced a cable tie fixation method using 6-0 polypropylene for subluxated multifocal IOL with C-loop or double C-loop haptics. After passing the 6-0 polypropylene monofilament under the optic-haptic junction, the other end of the strand was taken out of the eye after passing it above the optic-haptic junction. A knot was made at one end, and the opposite strand was passed through the knot to form a loop. Both ends of the monofilament were tugged to make the loop fixed to the optic-haptic junction smaller. Both ends of the monofilament were externalized 2.5 mm posterior to the limbus using a 30 G needle. Another 6-0 polypropylene monofilament was tied to the opposite optic-haptic junction and scleral fixation was performed. While checking the IOL centration, the four ends of the 6-0 polypropylene monofilaments were heated with a cautery to form flanges.Conclusions and importanceA four-flanged intrascleral fixation technique involving a cable tie-shaped loop using 6-0 polypropylene could provide stable IOL fixation without damage for subluxated or dislocated IOLs with C-loop or double C-loop haptics.

Modified sewing machine technique for iridodialysis repair, intraocular lens relocation, iris coloboma repair, Cionni ring fixation, and scleral-fixated intraocular lens.

Project description:The purpose of this study is to report the modification of sewing machine technique for iris dialysis repair (MSMT) and its usefulness in managing other conditions such as intraocular lens (IOL) subluxation, iris coloboma, Cionni ring for zonular dialysis, and for scleral-fixated IOL. MSMT was based on sewing machine principle using a prethreaded 26G/30G needle with prolene suture for minimally invasive iris dialysis repair in a closed chamber manner. So far, eight patients (trauma - 3, surgical complication - 5) underwent this procedure. This technique is further modified to extend its use for IOL relocation - 2, iris coloboma repair - 3, and Cionni ring fixation for zonular dialysis - 2, SFIOL - 5 patients. All 20 patients had good visual recovery and cosmetic outcome with minimal morbidity. To conclude, MSMT offers cost -effective, minimally invasive, easy to learn procedure with a potential to tackle several problems related with cataract surgery and iris defects, which even an average cataract surgeon can learn to perform when required. Further comparative studies with conventional techniques with large sample size are required to standardize this procedure.

Extraocular needle- guided haptic insertion technique of scleral fixation intraocular lens surgeries (X-NIT).

Project description:The most challenging step in sutureless scleral fixation of intraocular lens (SFIOL) is exteriorization of haptics. The conventional handshake technique has a learning curve since it involves intraocular handing over of haptics from one forceps to another. Here, we describe "extraocular needle-guided haptic insertion technique" (X-NIT), a novel technique of exteriorizing haptics that totally eliminates intraocular manipulations. This method involves sequential introduction of two bent 26-gauge needles through the sclera (pars plicata zone) into the eye which are brought out through a sclerocorneal wound. The intraocular lens haptics are threaded through these needles and exteriorized. Nineteen consecutive patients underwent surgery by this technique. There were no intraoperative complications. The mean best-corrected visual acuity (BCVA) of these patients at 1-month follow-up was 0.5 ± 0.3 (logarithm of the minimum angle of resolution) with 18 of 19 eyes showing one or more lines of improvement in BCVA. X-NIT is a safe, easy, cost-effective, and highly reproducible technique, especially for beginners.

Modified balanced two-string technique of internal scleral fixation of posteriorly dislocated intraocular lens.

Project description:Posterior dislocation of the intraocular lens (IOL) is a rare but potentially dangerous complication encountered by a cataract surgeon. We describe a modified balanced two-string technique of internally fixing a posteriorly dislocated rigid IOL using the pars plana approach in eyes which lack adequate capsular support. Five eyes of five patients underwent the procedure. All eyes had successful IOL refixation. One eye had mild temporal decentration. BCVA improved in all patients. Our technique is an alternate method of scleral fixation of posteriorly dislocated IOL with advantages of minimal postoperative astigmatism, minimal anterior segment manipulation, and good IOL centration.

A novel device for safe exteriorization of haptic in scleral fixation intraocular lens surgery.

Project description:The aim of this study was to describe a novel device that has been designed to facilitate anterior segment and novice surgeons to perform extraocular needle-guided haptic insertion technique (X-NIT) for scleral fixation intraocular lens surgery (SFIOL). We performed SFIOL surgery using X-NIT device in 21 eyes of 21 patients. The mean preoperative best-corrected visual acuity (BCVA) was 0.5 ± 0.2 logarithm of minimum angle of resolution (log MAR), which improved by one or more lines postoperatively in all eyes. There were no intraoperative complications. Postoperatively, we noted minimal corneal edema in one patient and dispersed vitreous hemorrhage in one patient. The sharpness and angulation of the needle and the haptic holding ability of silicone stopper were found to be satisfactory. The X-NIT device may potentially improve the safety of SFIOL procedures by minimizing intraocular maneuvers.

Sutureless 27-gauge needle-assisted transconjunctival intrascleral intraocular lens fixation: Initial experience.

Project description:The purpose of the study was to report our initial experience with the transconjunctival Intrascleral Intraocular Lens (SFIOL) fixation with modified Yamane's double-needle technique and flanged haptics.This was a prospective interventional study that enrolled 31 consecutive patients undergoing SFIOL with the modified Yamane's technique. All patients underwent comprehensive evaluation including uncorrected and best-corrected vision, intraocular pressure, ultrasound biomicroscopy, endothelial cell density, and macular thickness using optical coherence tomography (OCT). We excluded patients with visually significant coexistent pathology such as corneal scars, macular pathology, and glaucoma.The mean age of subjects was 57 ± 16.9 years and 23 were men (74%). Surgery was performed for aphakia following complicated cataract surgery in 10 eyes (32%), with lensectomy for subluxated/dislocated cataract in 6 eyes (19%), and with IOL explantation for subluxated/dislocated IOL in 15 eyes (48%). There were no intraoperative complications. Uncorrected visual acuity improved from median of 1.48 logarithm of minimum angle of resolution (logMAR) units (interquartile range [IQR] = 1.3-2 logMAR) at baseline to 0.3 logMAR (IQR = 0.2-0.4 logMAR) at 6 weeks (P < 0.001) which was maintained at 6 months. There were no significant changes in endothelial cell density (P = 0.34) and OCT-based macular thickness (P = 0.31) at 6 months. Two eyes had slight IOL decentration.Our initial experience suggests that the Yamane's technique for SFIOL is a simple procedure with a short-learning curve and is independent of scleral flaps, tunnels, sutures, and fibrin glue. Using widely available 27-gauge needle instead of 30-gauge thin wall needle as originally described by Yamane makes it possible for the use of various three-piece IOLs available globally. Further studies are required for widespread acceptance of this technique.

Comparison of flanged intrascleral intraocular lens fixation versus iris claw intraocular lens fixation: A retrospective study.

Project description:Purpose:To compare the visual outcome and complications of retropupillary fixated iris claw intraocular lens (IOL) and sutureless intrascleral IOL fixation using the flanged fixation technique at 1 year. Methods:In this retrospective study, eyes that underwent either iris claw or flanged SFIOL from January 2016 to July 2017 with a minimum of 1-year follow-up were enrolled. Improvement in visual acuity, intraocular pressure measurements, endothelial cell count, central macular thickness, and complications were compared between and within groups at 6 weeks, 3 months, and 1 year postoperatively. Results:Data from 150 eyes were analyzed (n = 90 in the iris claw group and n = 60 in the flanged SFIOL group). Posterior capsular rent was the most common indication for IOL implantation (n = 51, 34%). The iris claw and SFIOL groups were comparable in terms of demographics and baseline characteristics. There was significant improvement in uncorrected distance visual acuity (UCDVA) at 6 weeks in both groups (P = 0.77), and at 1 year, the UCDVA was comparable between groups (0.36 ± 0.32 in the iris claw group and 0.30 ± 0.28 in the SFIOL, P= 0.75). Transient elevation of intraocular pressure was seen slightly more in eyes with SFIOL (17%), while ovalization of the pupil was the main sequelae seen in the iris claw group (20%). Conclusion:Both iris claw IOL fixation and SFIOL using flange are viable options for surgical correction of aphakia. Visual outcomes are excellent at 6 weeks and are maintained till 1-year follow-up, and complication rates are acceptably low, although ovalization of pupil is common with iris claw IOLs.
