Combined cataract surgery and vitrectomy for recurrent retinal detachment

PURPOSE: To report our experience with combined cataract surgery, posterior chamber intraocular lens implantation, and pars plana vitrectomy in the management of recurrent retinal detachment (RD) and visually significant cataract. METHODS: Retrospective chart review of patients with cataract and recurrent RD who underwent combined cataract extraction, posterior chamber intraocular lens implantation, and pars plana vitrectomy between January 1991 and September 1998 at the Bascom Palmer Eye Institute. Sixteen eyes were included. All eyes had visually significant cataract and had undergone primary repair of the RD with encircling scleral buckle; eight eyes also had undergone pars plana vitrectomy during the primary repair. The technique of cataract extraction included phacoemulsification (10 eyes), extracapsular cataract extraction (5 eyes), and pars plana lensectomy (1 eye). All eyes underwent pars plana vitrectomy, membrane peeling, fluid-air exchange, endolaser treatment, and placement of a retinal tamponade. Perfluoropropane (C3F8) gas was used in 14 eyes, and silicone oil was placed in two eyes. RESULTS: The postoperative follow-up interval ranged from 4 to 64 months (mean, 16 months). Preoperative visual acuity ranged from 20/60 to hand motions and was better than 20/200 in 3 (19%) eyes. Postoperatively, 9 (56%) eyes improved to better than 20/200. Anatomic success was achieved after the initial reoperation in 13 (81 %) eyes. With further surgery, the overall success rate was 94%. CONCLUSIONS: Combined cataract surgery, posterior chamber intraocular lens implantation, and pars plana vitrectomy in selected patients with cataract and recurrent RD was successful in improving visual acuity and achieving retinal reattachment in most of these reoperated patients.

Combined lens and vitreoretinal surgery in patients with traumatic cataract and intraocular foreign body

AIM: To analyze the postoperative anatomical and functional outcomes as well as complications after combined phacoemul- sification, pars plana vitrectomy (PPV), removal of the intraocular foreign body (IOFB) and intraocular lens (IOL) implantation in patients with traumatic cataract and intraocular foreign body. METHODS: Medical records of 13 patients(13 eyes) with traumatic cataract and IOFB who had undergone combined phacoemulsification, PPV, foreign body extraction and IOL implantation were retrospectively analyzed. The postoperative follow-up ranged from 2 to 12 months. The main measure- ments of outcomes were the extraction success of cataract and intraocular foreign body, intraoperative and postoperative complications and the final best corrected visual acuity (BCVA). ·RESULTS: The mean age of 13 patients(10 male, 3 female )was 36.8 years (range: 17-65 years). All eight IOFBs were removed. Four intraocular lenses were implanted after vitrectomy intraoperatively. In 5 cases, intraocular lenses were implanted during the second operation. Intraocular lenses were not implanted in 4 cases. BCVA at last ranged from 0.8 to hand movement. BCVA was 0.5 or better in four eyes, 0.1 to 0.4 in five eyes, less than 0.1 in four eyes. Intraoperative complications were encountered in 3 patients. They had vitreous hemorrhage. Postoperative complications were encounter- ed in 2 patients. They had retinal detachment. The reoperations of the two patients were successful. CONCLUSION: The combined phacoemulsification, PPV, removal of IOFB and IOL implantation is safe and effective for patients with traumatic cataract and intraocular foreign body. The visual outcome depended primarily on the corneal or scleral wound and underlying posterior segment pathology and sites.

Application of Foldable Intraocular Lens in Multiple Types of Cataract

Objestive:To evaluate the clinical results of implantation of foldable intraocular lens in multiple types of cataract.Methods:This retrospective study comprised 162 eyes of 148 patients undergoing phacoemulsification and implantation of foldable intraocular lens,some of whom underwent combined pars plana vitrectomy or trabeculectomy of silicone oil removal.The period of follow-up was from 3 months to 17 months.Results:There is slight reaction postoperatively in all cases.The postoperative uncorrected visual acuite was from 0.05 to 1.2,patient with 0.6 or above acuity were 70.98%,A neodymium:YAG capsulotomy was required in 5eyes.Posterior capsule ruptured in 1 eyes,and a PMMA intraocular lens was implanted in ciliary sulcus.In one eye,a lens was removed because of recurrence of retina detachment.Conclusions:The application of foldable intraocular lens in multiple types of cataract is safe,and there is a slight postoperative reaction less complications,and fast visual asuity recovery.     

Combined pars plana vitrectomy and cataract surgery: outcome of phacoemulsification versus manual extracapsular cataract extraction through a sclerocorneal tunnel.

BACKGROUND AND OBJECTIVE: To compare the results of combined pars plana vitrectomy and cataract extraction with intraocular lens implantation by phacoemulsification versus manual extracapsular cataract extraction through a sclerocorneal tunnel. PATIENTS AND METHODS: Retrospective chart review of all patients who underwent combined pars plana vitrectomy with intraocular lens implantation and phacoemulsification or extracapsular cataract extraction through a sclerocorneal tunnel between March 1992 and July 2002. RESULTS: Fifty-four eyes of 51 patients were evaluated. Mean age was 69.68 +/- 9.11 years, and mean follow-up was 9 months. Phacoemulsification was performed in 35 cases (64%) and manual extraction in 19 cases (36%). Visual acuity improved from mean logarithm of the minimal angle of resolution 1.69 +/- 0.54 before surgery to 1.22 +/- 0.76 after surgery. There was a greater improvement of visual acuity in the phacoemulsification group (0.59 +/- 0.67) than in the extracapsular cataract extraction group (0.22 +/- 0.68) (P = .06). Final visual acuity was correlated to the vitreoretinal pathology. Ultrasound biomicroscopy showed well-positioned foldable or rigid intraocular lens in the bag or in the sulcus. CONCLUSION: Combined cataract extraction by phacoemulsification or extracapsular cataract extraction through sclerocorneal tunnel and pars plana vitrectomy are safe and effective procedures.     

Vitrectomy for retained lens fragments in the vitreous after phacoemulsification

PURPOSE: To assess the visual results, retinal detachment (RD) rate, incidence of glaucoma, and intraocular lens (IOL) placement after vitrectomy for removal of retained lens fragments in the vitreous after phacoemulsification. SETTING: Department of Ophthalmology, University Hospital of Lund, Lund, Sweden. METHODS: This retrospective noncomparative interventional case series included all cases of pars plana vitrectomy for removal of retained lens fragments from January 1997 through January 2000. RESULTS: Sixty-six eyes of 65 patients had pars plana vitrectomy with removal of the lens material over the 3-year period. Visual acuity on presentation was 0.1 or worse in 36 eyes (54%). Visual acuity after vitrectomy was 0.5 or better in 35 eyes (53%). The postoperative visual acuity was worse than 0.1 in 14 eyes (21%). Twenty-seven (56%) of the 48 eyes operated on within 1 week and 8 (44%) of the 18 eyes operated on later achieved a visual acuity of 0.5 or better. Twelve eyes (80%) that had secondary posterior chamber IOL implantation achieved an acuity of 0.5 or better. An RD occurred in 7 eyes (11%). CONCLUSIONS: There was no statistically significant difference in outcomes between those having vitrectomy the first few days after cataract surgery and those having it later, although there was a trend toward better results when the vitrectomy was done sooner. Secondary IOL implantation resulted in a good visual outcome. Retinal detachment was the most severe complication.
