“…35 Other studies have additionally shown that residual OVDs lodged in the trabecular mesh can prevent the outflow of aqueous fluid, thereby causing elevated IOP in the first 24 h after surgery. 36 Certainly, the retained OVD is not the only reason that increases IOP in the first postoperative day. The unappropriate wound closure, insufficient cortex cleaning, trauma to the iris and anterior chamber inflammation are well known other risk factors.…”

Purpose To compare and evaluate the results of phacoemulsification surgery involving and not involving an ophthalmic-viscosurgical-device (OVD). Methods A prospective, randomized controlled trial included 60 eyes of 60 patients scheduled to receive phacoemulsification surgery. In order of presentation, patients were randomized into two groups to undergo different surgical techniques: the OVD-free group ( n = 30) and the OVD group ( n = 30). Each patient’s operating time, total ultrasonography (U/S) time, cumulative dissipated energy (CDE), aspiration time, and volume of balanced salt solution (BSS) aspirated were recorded. At 1 day, 1 week, and 1 and 3 months postoperation, measurements of endothelial cell density (ECD) and intraocular pressure (IOP), were taken and compared between the groups. Results Total U/S time ( p = .567) and CDE ( p = .168) were similar between the groups. In the OVD group, operating time ( p = .011), aspiration time ( p < .001), and volume of BSS aspirated ( p < .001) were greater than in the OVD-free group. The change in ECD between the groups was not statistically significant at all visits ( p = .433, p = .147, p = .379, p = .534; respectively). Although IOP increased in the OVD group at 1 day postoperation ( p = .001), no difference emerged between the groups at 3 months postoperation ( p = .121). Conclusion Phacoemulsification surgery without an OVD took less time than with the OVD and caused no significant loss in ECD. Surgeons concerned about elevated IOP following cataract surgery should apply the OVD-free method.

“…However, there are studies which describe problems related with viscoelastic substance. The IOP elevation by viscoelastic substances is caused by a reduction of aqueous outflow due to blockage of the trabecular meshwork where the fluids exit the eye, which was first published in 1990 [18] and later confirmed by other authors in vivo and in vitro [10,22,23]. Therefore, complete removal of viscoelastic substance is recommended after IOL implantation.…”

“…Flare or Tyndall effect could be postoperatively detected after cataract surgery, which in part is frequent, but in excess that could be the manifestation of "toxic anterior segment syndrome" (TASS) after cataract surgery, and viscoelastic substance could be associated with this [23,24]. Also, an extra surgery time is necessary to introduce viscoelastic substance and to completely remove them from the anterior chamber, trying to avoid the problems previously described.…”

Life expectancy of the population increase and cataract development will affect all the people with aging. Cataract surgery, a worldwide performed procedure, evolves and progresses. However, different techniques exist, which could be selected for different cases. Any ideal technique should be safe, simple, fast, and easy to learn with good clinical outcome. This chapter will describe one technique to operate cataracts with those characteristics and to perform phacoemulsification cataract surgery without viscoelastic substance. Some advantages of this technique are related to avoiding viscoelastic potential problems, as postoperative intraocular pressure elevation or anterior chamber inflammation associated with viscoelastic. Moreover, a fundamental factor to remark is the difference between work into the anterior chamber with negative pressure or positive pressure. Because the anterior chamber is maintained by the balanced salt solution with the continuous irrigation without viscoelastic. Performing the capsulorhexis is easier. Other advantages are shorten surgical time, fewer economical cost, and potentially fewer complications. Some limitations are as follows: intraocular lens must be one piece foldable, and principally, patients with corneal endothelial pathology must be excluded. Tips, step-by-step surgery, recommendations, and evolution of the technique will be described, with the wish that many surgeons will try to perform Bianchi's method (bimanual, microincision phacoemulsification cataract surgery without viscoelastic substance) for your next patient.

Purpose: To evaluate corneal endothelial health after cataract surgery without viscoelastic substance (VS). Methods: A prospective, non-randomized, case-series study was developed, and phacoemulsification cataract surgery without VS was performed on 1324 eyes between September 2015 and September 2018. As main outcomes, mean endothelial cell density (ECD) and mean central corneal thickness (CCT) were assessed before surgery and then 6 and 12 months after surgery. Data are summarized as mean, standard deviation (SD), and 95% confidence intervals (CI). Results: A total of 1324 eyes were operated, and 31 were excluded by intraoperative complications. The mean ECD baseline was 2506 cells/mm2 (SD = 215, CI = 2494–2518); 6 months after surgery, it was 2328 cells/mm2 (SD = 213, CI = 2316–2340); and 1 year after surgery, it was 2265 cells/mm2 (SD = 214, CI = 2253–2277). In terms of percentage differences, the mean ECD decrease was 9.4% after 1 year. The mean preoperative CCT was 531.6 μm (SD = 34.8, CI = 529.7–533.5); 6 months after surgery, it was 537.7 μm (SD = 38.2, CI = 535.6–539.8); and 1 year after surgery, it was 537.9 μm (SD = 37.9, CI = 535.8–540.0). The mean CCT increased 1.2% 1 year after surgery. Conclusions: Phacoemulsification cataract surgery can be completely performed without VS, with very low intraoperative complications. The postoperative ECD and CCT changes occurred primarily during the first 6 months, and the changes decreased during the second semester.
