Phacoemulsification Cataract Surgery

Purpose To compare the surgical workload, complications, and visual outcomes using the three-dimensional visualization system with the conventional microscope in phacoemulsification cataract surgery. Design Prospective, non-randomized, open-label interventional study. Methods All patients underwent phacoemulsification cataract surgery using the three-dimensional visualization system or conventional microscope. Results Of the 203 eyes, 80 underwent surgery with the three-dimensional system while 123 underwent with the conventional microscope. No difference was noted in the total surgical duration, complication rates, and visual outcomes between the two groups. However, capsulorhexis was significantly faster using the conventional microscope while posterior chamber intraocular lens insertion was quicker using the three-dimensional system. In terms of cognitive workload comparison, no difference was seen in the surgeons’ heart rate, oxygen saturation levels, and surgery task load index total workload score and workload score for all six dimensions of the questionnaire, between the three-dimensional system and conventional microscope groups. As compared to baseline, the heart rate increased significantly during all surgical steps and at the end in both groups. When compared to baseline, the oxygen saturation levels were significantly raised during capsulorhexis, irrigation, and aspiration and posterior chamber intraocular lens insertion and at the end of the surgery in the three-dimensional group and during incision and at the end of the surgery in the conventional microscope group. Conclusions The duration of surgery, complications, and visual acuity outcomes remain unaffected while performing phacoemulsification cataract surgeries with the three-dimensional viewing system when compared to the conventional microscopes. Moreover, the surgeons’ cognitive workload too remains unaffected while utilizing this revolutionary three-dimensional surgical technology.

Phacoemulsification Cataract Surgery

Purpose: This study compared real-world safety and efficacy outcomes of cataract surgery performed with LenSx femtosecond laser-assisted cataract surgery or manual phacoemulsification cataract surgery procedures. Methods: A retrospective observational study used data from anonymised electronic medical records to compare mean cumulative dissipated energy, the proportion of eyes reaching emmetropia, mean change in best-corrected distance visual acuity and the proportion of eyes with post-surgical complications, including corneal oedema and posterior capsule opacification. Results were adjusted for multiple comparisons for primary and secondary objectives. Results: Data from 811 phacoemulsification cataract surgery and 496 femtosecond laser-assisted cataract surgery procedures were analysed. Mean cumulative dissipated energy was significantly lower for femtosecond laser-assisted cataract surgery (6.5 percent-seconds) than for phacoemulsification cataract surgery (14.3 percent-seconds; p < 0.0001) procedures. More femtosecond laser-assisted cataract surgery (81.2%) procedures achieved emmetropia (⩽ 0.5 dioptre) than did phacoemulsification cataract surgery (73.5%) procedures, although this difference was not statistically significant. Mean change in best-corrected distance visual acuity and the proportion of eyes with corneal oedema, posterior capsule opacification or other complications were not significantly different between cohorts when adjusted for multiple comparisons. Conclusions: In this single-centre, single-surgeon retrospective electronic medical record database study using divide and conquer technique, femtosecond laser-assisted cataract surgery was associated with significantly lower cumulative dissipated energy when compared to manual phacoemulsification cataract surgery. This supports the hypothesis that femtosecond laser-assisted cataract surgery involves less mechanical trauma, which might lead to more consistent refractive and safety outcomes than manual phacoemulsification cataract surgery, though such outcomes were found to be comparable in this study.

We report a case of bilateral iridoschisis with corneal oedema and a quantitative evaluation of the changes in iridotrabecular and iridocorneal contact before and after cataract surgery and after Descemet stripping automated endothelial keratoplasty (DSAEK). A 76-year-old woman with iridoschisis and cataracts, previously managed with laser iridotomy, experienced progressive vision loss. The preoperative iridotrabecular contact (ITC) index measured by anterior segment optical coherence tomography was 23.6% in the right eye and 24.4% in the left eye. Preoperative corneal oedema in the right eye was more severe than that in the left eye. Cataract surgery, followed by DSAEK, was performed in the right eye and subsequently in the left eye. Her visual acuity improved postoperatively, and the corneal oedema of both eyes was treated successfully. Moreover, the ITC index improved in both eyes, to 4.7 and 6.9% after cataract surgery and to 0 and 0% after DSAEK in the right and left eyes, respectively. Staged cataract surgery and DSAEK were effective for endothelial decompensation caused by iridoschisis. Additionally, we confirm that iridotrabecular and iridocorneal contacts improved after both surgical procedures not only after cataract surgery but also after DSAEK. This case report showed the clinical usefulness of the ITC index in the detection of changes after different surgical procedures.

Aim - to evaluate the clinical efficacy and features of use new three-dimensional visualization system "NGENUITY' in surgery of cataract with implantation of "pre-loaded" intraocular lens "AcrySof IQ Ultrasert" (ALCON). Materials and methods. We investigated the clinical results of using a 3D visualization system "NGENUITY' cataract surgery in 100 patients (100 eyes) age of 64.3+6.1 years; 83 women and 17 men. Implanted monofocal IOLs "AcrySof IQ Ultrasert" company "Alcon" with a goal refraction Em+0,5 diopters with the use of navigation systems "VERION" (Alcon). Results. There were no intraoperative or postoperative complications. Examination of patients was carried out on 1 and 7 days and 1 and 3 months after surgery. The postoperative period was smooth, without injections. As a result of treatment, uncorrected visual acuity in the distance was 0.74+0.02 (0.2 to 1.0) and depended on the fundus condition. The average sphericules clinical refraction 0,38+0,47 dioptres. Refraction of the target was achieved in 91% of patients. Loss of corneal posterior epithelial cells was 3.8+1.5%. The results of the use of 3D imaging system "NGENUITY" in cataract surgery suggest that it has a number of significant advantages over the use of traditional methods of modern microsurgery. Summary. 1. A new three-dimensional visualization system "NGENUITY 3D Visualization System" provides the surgeon much more than just improved visuals. 2. Practical development and further technological development of the system "NGENUITY 3D Visualization System" opens new scientific and practical prospects in cataract surgery. 3. The use of the new system "ULTRASERT Preloaded IOL Delivery System" the implantation of a monofocal IOL significantly optimizes the surgery of cataracts. 4. New technological features of the system design "ULTRASERT Pre-loaded IOL Delivery System" enable to eliminate the risk of infection and damage to the lens, allow quick and stable placement in the capsular bag, a smooth postoperative period.
