Phacoemulsification Cataract Surgery

Abstract Background Cataract development is common in phakic eyes filled with silicone oil (SO), necessitating subsequent cataract removal. This study evaluated the refractive outcome in eyes filled with SO undergoing phacoemulsification cataract surgery (PCS). Methods This retrospective study evaluated patients with SO tamponade who were scheduled for PCS. Results Subjects (n=26) were followed-up for 29.5 ± 13.9 months after cataract surgery. The median spherical equivalent refraction (SER) was +5.3 D (interquartile range [IQR] +2.9 to +6.7) before PCS, and +3.4 D (IQR +2.0 to +4.4) after PCS. Within the follow-up period retinal reattachment after SO removal was achieved in 15 out of 26 eyes (57.7%). In 13 eyes assessment of refraction after SO-removal was possible, and showed a myopic shift of -4.6 D (IQR -2.9 to -7.3) in the SER. After SO removal, 5 of 13 eyes (38.5%) were within ±1.0 D of the target refraction, while 9 out of 13 eyes (69.2%) were within ±2.0 D. Conclusions The refractive outcome after PCS for eyes filled with SO is less predictable than that for normal eyes. Some of the eyes undergoing silicone oil injection may require long-term tamponade.

AIM: To evaluate the refractive and long-term outcome of eyes filled with silicone oil (SO) undergoing phacoemulsification cataract surgery (PCS). METHODS: This retrospective study evaluated patients with SO tamponade who were scheduled for PCS. RESULTS: Subjects (n=26) were followed for 29.5±13.9mo after cataract surgery. The median spherical equivalent refraction (SER) was +5.3 D [interquartile range (IQR) +2.9 to +6.7] before PCS, and +3.4 D (IQR +2.0 to +4.4) after PCS. Within the follow-up period retinal reattachment after SO removal was achieved in 15 out of 26 eyes (57.7%). In 13 eyes assessment of refraction after SO-removal was possible, and showed a myopic shift of -4.6 D (IQR -2.9 to -7.3) in the SER. After SO removal, 5 of the 13 eyes (38.5%) were within ±1.0 D of the target refraction, while 9 out of the 13 eyes (69.2%) were within ±2.0 D. CONCLUSION: In our study, the refraction after PCS for eyes filled with SO manifested low predictability, as did the myopic shift following SO removal. A significant percentage of the eyes that underwent SO administration required a long-term tamponade.

Phacoemulsification Cataract Surgery

AIM: To update and investigate the clinical outcomes and complications between femtosecond laser-assisted cataract surgery (FLACS) and conventional phacoemulsification cataract surgery (CPCS). METHODS: A Meta-analysis was performed using databases, including Pubmed, Embase, and the Cochrane library. At least one of the clinical outcomes and/or complications data in each included randomized controlled trials (RCT) was reported. The quality of the RCT was assessed with the Cochrane risk assessments tool. RESULTS: Overall, 25 RCTs including 3781 eyes were included. No statistically significant difference detected between FLACS and CPCS in terms of corrected distant visual acuity (CDVA), uncorrected distant visual acuity (UDVA), and central corneal thickness (CCT) at the long-term follow up, although FLACS showed better CDVA at 1wk postoperatively, and less increase in CCT at 1d and 1wk. FLACS had better postoperative endothelial cell count (ECC) at 1 and 4-6wk, while there was no significantly difference between FLACS and CPCS at 1d, 3 and 6mo [weighted mean difference (WMD): 51.54, 95% confidence interval (CI): -5.46 to 108.54, P=0.08; WMD: 48.52, 95%CI: -17.54 to 114.58, P=0.15; WMD: 12.17, 95%CI: -48.61 to 72.94, P=0.69, respectively]. Postoperative endothelial cell loss (ECL) of the FLACS was significantly lower than that of the CPCS at 1, 4-6wk, and 3mo (P=0.02, 0.008, 0.03, respectively). However, there was no significant difference between two groups at 6mo (WMD: -30.36, 95%CI: -78.84 to 18.12, P=0.22). No significant difference was discovered with respect to the macular edema [odds ratio (OR): 0.93, 95%CI: 0.42 to 2.05, P=0.85], capsular complication excluding posterior capsular tears (OR: 0.79, 95%CI: 0.42 to 1.50, P=0.47) and intraocular pressure change (OR: 0.82, 95%CI: 0.39 to 1.72, P=0.60). However, posterior capsular tears were more common in CPCS group (OR: 0.12, 95%CI: 0.01 to 0.98, P=0.05). The effective phacoemulsification times were significantly lower in the FLACS group compared to the CPCS group (WMD: -0.78, 95%CI: -1.23 to -0.34, P=0.0006). CONCLUSION: No statistically significant difference is discovered between FLACS and CPCS in clinical outcomes at the long-term follow up. However, higher rate of posterior capsular tears is detected in patients receiving CPCS.

Phacoemulsification Cataract Surgery

Abstract Background Accumulating evidence suggests that refractive stabilization occurs rapidly following small incision cataract surgery. Nonetheless, many guidelines still suggest waiting four to 6 weeks before prescribing corrective lenses. This study was undertaken to supplement the existing literature regarding refractive stabilization, and evaluate multiple contributing factors that could dissuade clinicians from confidently correcting refractive error in the early post-operative course following routine cataract surgeries. Methods Adult patients undergoing phacoemulsification cataract surgery with uncomplicated surgeries and post-surgical courses at the Calgary Ophthalmology Centre (Calgary, Alberta, Canada) were included in this prospective observational case series. Exclusion criteria included known corneal dystrophies, infectious keratitis, complicated surgery or toric/multifocal IOLs. Data was collected at weekly intervals for a total of 6 weeks. Collected data included autorefraction, visual acuity, corneal pachymetry, and effective lens position. Results One hundred six eyes of 104 patients were included in this study. Post-operative sphere, cylinder and spherical equivalent were not significantly different at any post-operative week compared with week six, and 80–86% of patients were within 0.5D of last follow-up spherical equivalent at any week. The secondary outcomes of central corneal thickness, effective lens position and visual acuity did, however, exhibit significant differences between early post-operative weeks and last follow-up values. Conclusions These data suggest that refractive error can be effectively measured and corrected as early as one-week post-operatively in the majority of patients, though other measures of post-operative stability including central corneal thickness, effective lens position and visual acuity can require up to 4 weeks to stabilize. Thus a conservative and pragmatic approach may be to wait until 4 weeks post-operatively prior to obtaining refractive correction following uncomplicated phacoemulsification cataract surgery.

We report a case of a 57-year-old man, who underwent right eye silicone oil injection as a part of his surgical treatment for rhegmatogenous retinal detachment. Following this, on the first postoperative day, he developed acute postoperative intraocular inflammation. There was circumciliary congestion, diffuse corneal oedema, anterior chamber (AC) reaction, hypopyon and a pupillary membrane. The AC had not been entered during the surgery. No patients, who had been operated on the same day, or with the materials having the same batch number, developed similar reactions. We started the patient on hourly topical steroids and cycloplegics after which the patient’s condition showed gradual improvement. At the 2 weeks follow-up appointment, his pupillary membrane had completely contracted and the AC was quiet. This case highlights a clinical picture of acute postoperative silicone oil-induced ocular inflammation, which was resolved through medical management.

Suturing Methods

PurposeTo explore the long-term efficacy of novel choroidal suturing methods including trans-scleral mattress suturing (TSS) and intraocular suturing (IOS) in the treatment of choroidal avulsion.DesignProspective cohort, hospital-based study.MethodsA total of 24 patients who were diagnosed with choroidal avulsion were enrolled in this study. The demographic characteristics, baseline information of trauma, best-corrected visual acuity (BCVA), and intraocular pressure (IOP) were collected before surgery, and the anatomic abnormities of the globe were recorded before or during surgery. All patients were diagnosed with choroidal avulsion and underwent choroid suturing treatment during vitrectomy, postoperative functional variables including BCVA and IOP, anatomic variables including retinal and choroidal reattachment rate, and silicone oil migration rate, which were recorded at the regular follow-ups at least 1 year after surgery.ResultsAll patients with open globe injury involved zone III, 70.8% of the patients presented with two quadrants of the avulsed choroid, and 29.2% with one quadrant involved; moreover, all patients had complications with retinal detachment (RD), of which 58.3% of patients had closed funnel retinal detachment. TSS was applied in nineteen patients and IOS in five patients. Postoperatively, a significant improvement on LogMAR BCVA was observed at each follow-up from 3.57 ± 0.69 before surgery to 2.82 ± 0.98 at the last follow-up (p < 0.05), and the proportion of no light perception (NLP) was also reduced from 69.6 to 37.5%. IOP was markedly elevated from 6.4 ± 4.1 mmHg preoperatively to 11.3 ± 4.3 mmHg at the last follow-up (p < 0.05). Choroidal reattachment was achieved in 91.7% of patients; two patients were observed with silicone oil migration at 3 months after surgery and underwent drainage of suprachoroidal silicone oil and sclera buckling. Meanwhile, retinal attachment was observed in 95.8% of patients, only one patient developed partial RD due to postoperative proliferative vitreoretinopathy, and secondary vitrectomy was performed; all patients were observed with complete retinal and choroidal attachment at the last follow-up. Eventually, four patients were silicone oil-free, and 20 patients were silicone oil-dependent.ConclusionsChoroidal suturing proved to be an effective method to fix the avulsed choroid, which greatly improved the BCVA and maintained the IOP, and efficiently increased the choroidal and retinal reattachment rate and preservation of the eyeball.

Purpose: To report a case of endophthalmitis and retinal detachment after injury caused by an animal inoculation needle. Case summary: A 39-year-old man received an injury to his left eye with an animal inoculation needle while vaccinating a pig came to the hospital due to decreased visual acuity. At initial presentation, the best-corrected visual acuity in the left eye was “counting fingers,” and slit lamp examination revealed corneal lacerations, anterior capsule rupture, and traumatic cataract. Ultrasonography showed no specific findings in the vitreous and retina. Primary corneal suture, phacoemulsification, anterior vitrectomy due to rupture of the posterior capsule and vitreous prolapse, intraocular lens implantation, and intravitreal antibiotic injection were performed. On day 1 postoperatively, vitrectomy, anterior chamber irrigation, intravitreal antibiotic injection, and silicone oil injection were performed as signs of endophthalmitis, such as hypopyon and retinal tear, and focal retinal detachment were observed during surgery. Silicone oil removal was performed 7 months after the operation and the best-corrected visual acuity was 0.6. There has been no recurrence during follow-up. Conclusions: This is the first report in Korea of ocular injury caused by an animal inoculation needle. If the fundus is not observed in such injuries, there is a possibility of endophthalmitis and retinal detachment and early vitrectomy should be considered.

Prospective Comparative Study

Aim. Functional and morphological macular study after cataract surgery in a group of diabetics without diabetic retinopathy compared to nondiabetics to evaluate the effect of surgical oxidative stress on diabetic retina.Methods. Prospective, comparative study. Preoperative eye exam, best corrected visual acuity (BCVA) measured by ETDRS letters, and optical coherence tomography (OCT) were followed by standard cataract surgery. The follow-up visits at 1, 3, and 6 months postoperatively included BCVA, OCT, and microperimetry, to analyze changes within and between the groups.Results. The BCVA improved significantly in diabetics and controls: 64.2 to 81.0 and 61.9 to 82.1 ETDRS at 6 months, respectively. The central macula at OCT significantly thickened in both groups, while the central 5 fields, corresponding to the microperimetry area, subclinically thickened from 284.20 to 291.18 μm at 6 months only in diabetics (p=0.026). A matching slight decrease in the microperimetry sensitivity from 1 to 6 months was found also only in diabetics, with mean average difference −0.75 dB (p=0.04).Conclusion. Underlying diabetes does not influence the surgical outcome in diabetics without diabetic retinopathy. However, slight thickening of wider macula and corresponding decrease in retinal sensitivity observed in diabetics 6 months postoperatively might influence visual function on long term.
