In this study, the technique and results of iris-claw intraocular lens (IOL) implantation with corneal incision and single paracentesis were presented. Eighteen eyes of 18 patients who underwent iris-claw implantation surgery with a single paracentesis were included in this prospective study. Iris-claw lens was grasped by its forceps and placed into the anterior chamber through superior corneal opening. While IOL was held by forceps, a blunt enclavation spatula was introduced through inferior paracentesis. Then the spatula was directed toward underneath of iris through pupil and toward sides where iris was entrapped into the claw by gentle push of iris through the slotted center of the lens haptics. Mean age of patients was 54.28±25.21 years (7-76 years). Mean anterior chamber depth was 4.07±0.32 mm and mean keratometric power was 43.01±2.73 D. Preoperative BCVA was 20/63 or better in 8 (44.4%) patients. At the first postoperative month BCVA was 20/63 or better in 14 (77.8%) patients. Preoperative mean spherical refraction was +11.05±2.62 D, preoperative astigmatism was 2.15±0.85. Postoperative mean spherical refraction was - 0.58±0.25 D and mean astigmatism was - 1.92±0.67 D. The most frequent postoperative complication was mild corneal edema seen in three patients that resolved completely during the first week with medical treatment. Irisclaw IOL implantation can be performed easily with corneal incision and single paracentesis. Single paracentesis does not increase surgical time or cause inconvenience during the procedure.

BACKGROUND Visual rehabilitation of aphakic patients include spectacle correction, contact lenses, and primary or secondary intra ocular lens (IOL) implantation. Spectacles are rarely used nowadays because of limited visual field, aniseikonia and peripheral refractive errors. Contact lenses are other options for correcting aphakia but can cause a lot of corneal complications. Options for correction of aphakic patients with lack of adequate capsular support include anterior chamber IOL (ACIOL), scleral fixated IOL (SFIOL), and iris fixated IOL. Implantation of a retropupillary IC-IOL provides the benefits of a PCIOL, and the duration of the surgery is also less. The retropupillary IC-IOL because of its position lowers the risk of endothelial decompensation is a better option. We wanted to evaluate the functional outcomes of retropupillary iris claw lens implantation. METHODS Secondary implantation of IC-IOL was done in 50 surgical aphakic eyes as a result of intraoperative posterior capsular rent with zonular dialysis (N = 43, 86 %) & large (> 7 clock hours) zonular dehiscence (N = 7, 14 %). Follow up was done on 1 st day, 7th day, 1 month, 3 months and 6 months. RESULTS 22 males and 28 females in the age group 40 - 78 years were operated. 78 % eyes (N = 39) had vision better than 6 / 12 while only 10 % eyes (N = 5) had < 6 / 60 vision and the remainder 12 % (N = 6) had vision between 6 / 18 & 6 / 36. Complications like acute postoperative iritis (N = 18, 36 %) pupillary distortion (N = 15, 30 %), pigment clumping (N = 10, 24 %), iris chaffing (N = 9, 21 %), secondary glaucoma (N = 5, 12 %) and IOL decentration (N = 3, 7 %) were seen. The mean difference in central endothelial counts before surgery and 6 months after surgery was 109 cell / mm2 (5.92 %). CONCLUSIONS Iris claw lens gives the dual benefit of good visual acuity and less complication rate in aphakic patients with lack of adequate capsular support.

Purpose:  To determine the Anterior Chamber depth and Intraocular pressure change following uncomplicated phacoemulsification. Study Design:  Quasi experimental study. Place and Duration of Study:  Layyton Rehmatullah Benevolent Trust Free Eye and Cancer Hospital, Lahore from 16/12/2017 to 15/06/2018. Methods:  One hundred and thirty nine patients who came to Layyton Rehmatullah Benevolent Trust Free Eye for phacoemulsification and IOL implantation were included in the study. Anterior Chamber depth was measured with IOL Master and intraocular pressure was determined using Goldmann Applanation Tonometer one day before and one month after surgery. Data was recorded on a self-designed proforma. Comparison between pre- and post-operative data with respect to change was analyzed by chi-square test. P-value ≤ 0.05 was considered significant. Results:  The mean intra-ocular pressure dropped from 14.36 ± 4.19 mmHg to 12.14 ± 4.26 mmHg 1 month after surgery with a mean drop of 2.21 ± 0.65 mmHg while the mean anterior chamber depth increased from 2.31 ± 0.08 mm to 3.59 ± 0.37 mm with a mean increase of 1.29 ± 0.36 mm. There was no statistically significant difference in the mean change of intra-ocular pressure and anterior chamber depth across various subgroups based on patient’s age, gender and duration of cataract. Conclusion:  Phacoemulsification and IOL implantation not only improves the visual acuity by removing the cataract but also deepens the anterior chamber and decreases intra-ocular pressure, which can have a beneficial effect in glaucoma patients. Key Words:  Phacoemulsification, Cataract, Intraocular pressure, Lens, Anterior chamber depth.

Visual rehabilitation in aphakia has been a challenge with a wide variety of surgical options available for ophthalmologist. We report the visual outcome with retropupillary iris claw lens secondary to intra operative complications and secondary implantation in aphakia. An interventional study on 4 eyes of 4 patients was conducted. Preoperative visual acuity, slit lamp examination and fundus examination were carried out. Anterior vitrectomy and retropupillary fixation of iris claw lens were done. The primary outcome measure was best-corrected visual acuity and secondary postoperative complication was recorded at various intervals. All patients had visual acuity of ≥6/18 postoperatively. Sutureless retropupillary iris claw intraocular lens implantation is a good alternative of scleral-fixated intraocular lenses in aphakic patients.

Aim. To study the changes of anatomic and topographic characteristics of the eye anterior segment after uncomplicated cataract phacoemulsification using corneal incision with intraocular soft lens implantation. Methods. The data of ultrasound biomicroscopy and noncontact tonometry of 58 eyes (56 patients, 32 females, 24 males aged 54 to 78 years) before and after cataract phacoemulsification were analyzed. Paitents with survived ocular trauma, refractive keratoplasty, glaucoma, uveitis, and surgical complications (incomplete capsulorrhexis, posterior capsule rupture, ciliary zonule disinsertion, corneal burn). Apart from the common examinations (visual acuity testing, tonometry, tonography, eye A- and B-ultrasonography, biomicroscopy), all patients underwent eye ultrasound biomicroscopy. Results. Anterior chamber depth increased from 2.73±0.10 to 4.17±0.06 mm (p ≤0.001). Trabecula-iris distance measured at 500 μm from the scleral spur, increased from 0.38±0.02 to 0.47±0.02 mm (p ≤0.001). Anterior chamber angle increased from 28.69±1.87 to 42.73±1.56 degrees (p ≤0.001), the angle between the iris and the sclera increased from 32.78±1.39 to 41.36±0.84 degrees (p ≤0.001), the angle between the sclera and ciliary processes increased from 39.48±1.29 to 45.30±1.16 degrees (p ≤0.001). Intraocular pressure according to the non-contact tonometry data decreased from 18.16±1.29 to 13.55±0.95 mm Hg (p ≤0.001). Conclusion. Anterior chamber depth, trabecula-iris distance, anterior chamber angle, the angle between sclera and iris and the angle between sclera and ciliary processes increased significantly after phacoemulsification with intraocular lens implantation. Intraocular pressure decreased significantly according to the non-contact tonometry data.
