Topical anesthesia for transpupillary silicone oil removal combined with cataract surgery

PURPOSE: To assess safety of topical anesthesia for transpupillary silicone oil removal in combination with cataract surgery. SETTING: Department of Ophthalmology Mannheim, University of Heidelberg, Mannheim, Germany. METHODS: The clinical interventional study included 37 consecutive patients having transpupillary silicone oil removal combined with cataract surgery. Without exception, surgery was carried out in topical anesthesia for all patients. During the study period, there were no patients having transpupillary silicone oil removal in another type of local anesthesia than topical anesthesia. Topical anesthesia was achieved with oxybuprocaine 0.4% eyedrops installed 4 to 5 times prior to surgery. Cataract surgery was performed using the clear cornea technique with implantation of a foldable intraocular posterior chamber lens. Silicone oil was released through a planned posterior capsulotomy during cataract surgery prior to implantation of the intraocular lens (IOL). RESULTS: For all patients, surgery could be carried out in topical anesthesia without switching to peribulbar or any other type of anesthesia. None of the patients complained about severe pain intraoperatively or postoperatively. No severe complications such as expulsive hemorrhage, luxation of the IOL, or iris incarceration were encountered in any of the surgeries. CONCLUSION: Transpupillary silicone oil through a planned posterior capsulotomy during cataract surgery may be performed in topical surgery.     

Phacoemulsification combined with transpupillary removal of silicone oil and intracapsular intraocular lens implantation

AIM: To estimate the effectiveness of phacoemulsification and foldable intraocular lens (IOL) implantation combined with transpupillary silicone oil removal. METHODS: There were 168 eyes of 168 candidate patients with cataract and silicone oil-filled eyes recruited in our study. All of the patients received the intraocular silicone oil removal surgery by transpupillary drainage and cataract extraction by phacoemulsi?cation. Then the IOL implantation were also performed through corneal incision. RESULTS: The surgery was successfully completed in all eyes. Best corrected visual acuity (BCVA) and postoperative complications were recorded in three months after surgery. There were 143 eyes with BCVA improved, otherwise 25 eyes remained stable at the last follow-up visit. The mean BCVA statistically improved from 20/400±0.02 to 20/100±0.15 (P<0.001) and mean postoperative IOP was 13.85±2.18 mm Hg (P=0.415). No intra-operative complications were reported. CONCLUSION: Phacoemulsi?cation combined with transpupillary removal of silicone oil is a safe and simple effective method. In general, it enables quick recovery of visual acuity with less complication rate.     

Combined phacoemulsification and transpupillary drainage of silicone oil: results and complications

AIM: To review retrospectively 74 consecutive cases of combined phacoemulsification and transpupillary drainage of silicone oil. METHODS: Candidate patients for intraocular silicone oil removal and cataract extraction underwent combined phacoemulsification and transpupillary drainage of silicone oil through a planned posterior capsulorrhexis and without the use of a pars plana infusion line. RESULTS: The retina remained attached in 59 (79.7%) patients postoperatively. In this success group, the postoperative visual acuity improved in 42 (71.2%) patients. There was no association between age, duration of silicone oil tamponade, preoperative diagnosis, macular status or number and nature of previous surgery, and the incidence of redetachment following silicone oil removal. CONCLUSION: Combined phacoemulsification and transpupillary drainage of silicone oil is a safe and reliable technique that offers the main advantage of diminished surgical trauma.     

Cataract extraction combined with trans-pupillary silicone oil drainage by planned posterior capsulorhexis

BACKGROUND: A cataract is frequently observed after pars plana vitrectomy with silicone oil endotamponade. PATIENTS AND METHODS: Forty-three consecutive patients underwent cataract surgery combined with transpupillary removal of silicone oil. After phacoemulsification of the lens material through a sclerocorneal tunnel incision, a planned posterior capsulorhexis with a diameter of 3-4 mm was performed. By injecting saline through the capsulorhexis into the vitreous cavity, the silicone oil was rinsed out. Widening of the sclerocorneal tunnel facilitated the drainage of the silicone oil through the pupil and tunnel. After ophthalmoscopic evaluation of the fundus, a plano-convex PMMA posterior chamber lens was implanted into the capsular bag or ciliary sulcus, and the corneoscleral tunnel was closed by a 10-0 nylon suture. RESULTS: Depending on the underlying retinal disease the visual acuity improved in some eyes. Silicone oil bubbles left behind in the vitreous cavity were smaller than 0.5 mm in diameter. Persisting corneal decompensation or a clinically detectable cystoid macular edema related to cataract surgery did not occur. Due to the posterior capsulorhexis, secondary cataract did not develop postoperatively. Small postoperative vitreous hemorrhages resolved during the first three post-operative days. Retinal detachment recurred in 11 eyes (11/42 or 26.2%). In one eye, dislocation of the pseudophacos occurred which had to be corrected surgically. Since the pars plana region remained untouched, direct retinal lesions in the periphery of the fundus or marked vitreous hemorrhages were not encountered. CONCLUSIONS: Silicone oil removal can be combined with cataract surgery with transpupillary drainage of the silicone oil.     

Cataract Surgery and Transpupillary Silicone Oil Removal Through a Single Scleral Tunnel Incision Under Topical Anesthesia; Sutureless Surgery

The author evaluated the results of combined cataract extraction and transpupillary silicone oil removal through a single scleral tunnel incision, in eyes that had undergone pars plana vitrectomy with silicone oil tamponade. Twenty-four of the 46 eyes were operated on under topical anesthesia with Blumenthal mode mini-nucleus manual extracapsular cataract extraction technique (mini-nuc ECCE), and silicone oil was removed passively through planned posterior capsulorhexis via the scleral tunnel, followed by endocapsular intraocular lens (IOL) implantation. The operation was completed without any suturing. The remaining 22 eyes were similarly operated on with the same cataract extraction technique, but in these cases silicone oil was classically aspirated actively through pars plana sclerotomies. Results were evaluated by visual acuity measurement, duration of operation, and complications. The transpupillary silicone oil removal group had significantly less vitreous hemorrhage (0- 31.8%) and posterior capsule opacification (0-36.4%). Also, the mean duration of the operation was significantly shorter in this group. There was no significant difference between the two groups with regard to postoperative recurrence of retinal detachment (12.5-18.1%) and visual acuity outcome. The combination of mini-nuc ECCE with transpupillary silicone oil removal compares favorably with the combination of silicone oil aspiration through pars plana sclerotomies. This combined technique allows the surgeon to perform the operation under topical anesthesia and no sutures are required. The intervention period is shorter and no posterior capsule opacification or vitreous hemorrhage develops.     

Phacoemulsification with transpupillary silicone oil removal and lens implantation through a corneal incision using topical anesthesia

PURPOSE: To evaluate phacoemulsification combined with transpupillary silicone oil removal and foldable intraocular lens (IOL) implantation through a single corneal incision and planned posterior capsulorhexis after pars plana vitrectomy using topical anesthesia. SETTING: Department of Ophthalmology, University of Bari, Bari, Italy. METHODS: This noncomparative nonrandomized noncontrolled interventional case series comprised 34 consecutive patients (34 eyes). The mean age of the 25 men and 9 women was 54.4 years +/- 13.3 (SD). A mean of 8.2 +/- 9.4 months after silicone oil injection, patients had phacoemulsification with transpupillary silicone oil removal and foldable acrylic IOL implantation through a single corneal incision and a planned posterior capsulorhexis under topical anesthesia. Patients were operated on by the same surgeon. Visual acuity, the frequency of retinal redetachment, secondary cataract and vitreous hemorrhage formation, subjective pain and discomfort, the duration of surgery, and intraocular pressure (IOP) were noted. The mean follow-up was 9.4 +/- 5.1 months (range 4 to 21 months). RESULTS: Vision improved or stabilized in 88.2% of eyes. Retinal redetachment occurred in 4 eyes (11.8%) and transient vitreous hemorrhage in 1 (2.9%). All patients reported minimal discomfort during the procedure. The mean duration of surgery was 17 +/- 4 minutes. There was no significant intraoperative or postoperative IOP variation. CONCLUSIONS: Combined phacoemulsification, transpupillary silicone oil removal, and IOL implantation through a single corneal incision under topical anesthesia was safe and effective. In general, the visual outcomes were good with improvement in visual acuity.     

Cataract surgery and silicone oil removal: visual outcome and complications in a combined vs. two step surgical approach

PURPOSE: To compare visual outcome and complications of two surgical strategies for patients who needed cataract surgery and silicone oil removal. METHODS: A prospective, nonrandomized study was performed to compare two groups of patients who had cataract surgery and silicone oil removal from April 1998 to January 2002. From April 1998 to November 1999, patients had two surgical sessions with cataract surgery before silicone oil removal (Group 1), and from December 1999 to January 2002, patients underwent combined cataract surgery and silicone oil removal in a single session (Group 2). RESULTS: Thirty-five patients were included in each group. The postoperative visual acuity improved by at least two lines of Snellen in 13 patients (37.1%) in Group 1 and 15 (42.8%) patients in Group 2 (P=0.63). The mean visual improvement was 0.12 lines and 0.13 lines in groups 1 and 2 (P=0.62). Complications in groups 1 and 2 included transient intraocular pressure rise (25.7% versus 28.5%), retinal detachment (14.2% versus 11.4%), fibrin reaction (5.7% in both groups), and persistent intraocular pressure rise (2.8% in both groups). CONCLUSION: The visual outcome and complication rates were similar in both groups. Combined surgery offers the advantages of a single surgical event and a faster visual rehabilitation. We therefore suggest a surgical approach with combined cataract surgery and silicone oil removal in selected patients with a stable retinal situation.     

Evaluation of the results of cataract surgery in eyes after silicone oil removal

PURPOSE: To evaluate the results of cataract surgery in eyes after silicone oil removal and comparison of surgical technics. MATERIAL AND METHODS: Eighty-four eyes of 80 patients underwent cataract extraction and IOL implantation after vitrectomy with silicone oil, after its removal. In 50 eyes of group A cataract surgery was performed using the ECCE procedure, in 20 eyes of group B-phacoemulsification was done and in 14 eyes of group C cataract surgery was performed simultaneously with silicone oil removal. Ten eyes of the control group K underwent cataract extraction without IOL implantation. The follow-up was 15.5 +/- 11.2 months. RESULTS: Visual acuity of 6/60 or better was achieved in 65% of eyes. Statistically significant improvement in visual acuity was observed after cataract surgery, compared to the results after vitrectomy in the study group and in the control group. The most frequent complication was posterior capsule opacification, which occurred in 47 eyes (54.6%). CONCLUSIONS: Cataract surgery and IOL implantation in eyes after vitrectomy with silicone oil is safe and achieved visual acuity is similar or better, than before cataract formation. The usefulness of combined cataract surgery and silicone oil removal requires further studies.
