“…The same incision size is also present in the refractive difference by the Small Incision Lenticule Extraction (SMILE) method and according to research conducted by Zeren et al there is a change in tear secretion after refractive surgery with the SMILE method. This is caused by the severing of the nasociliary longus nerve fibers which are the last branch of the ophthalmic nerve, cranial nerves V. The decrease in sensitivity causes negative feedback to the motor nerve components, sympathetic and parasympathetic, which act on the lacrimal gland causing a decrease in tear secretion and cause complaints of tears dry eye in patients after cataract surgery 10,11 . This is relevant to research conducted by Retnaniadi, et al that there is a decrease in tear secretion after surgery either by the EKEK technique or the SICS technique in cataract patients due to damage to the corneal nerve fibers.…”

Background: Cataract is a serious problem in the world because it is the biggest cause of blindness in the world. Cataract healing can only be done with operative measures, one of them is phacoemulsification. The phacoemulsification technique is the latest operative technique for cataract healing but both conventional techniques or phacoemulsification techniques can cause a decrease in tear secretion after cataract surgery. The reduction in tear secretion can be evaluated using the Schirmer I test. In this study an analysis of differences in tear secretion before and after phacoemulsification surgery.Aims: Knowing, comparing, and analyzing the differences in tear secretion before and after phacoemulsification surgery using the Schirmer I test.Methods: 22 cataract eyes consisting of 15 patients who will undergo phacoemulsification surgery were collected by consecutive sampling at the Sultan Agung Eye Center, Sultan Agung Hospital, Semarang from August to September 2019, examined using the Schirmer I test. After the data was collected, data analyzed with Wilcoxon rank test.Results: A total of 15 cataract patients consisting of 10 female patients and 5 male patients with a total of 22 eye samples. The average tear secretion before and after phacoemulsification surgery was 12.77 ± 2.74 mm and 11.00 ± 1.95 mm. Data were tested with the Wilcoxon rank test, p = 0,000 (p <0.05) which showed a difference in average tear secretion before and after phacoemulsification.Conclusion: There are differences in tear secretion before and after phacoemulsification surgery.

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.

“…8,9 To avoid those costs, risks, and unwanted outcomes, various phacoemulsification techniques have been developed to be applied without OVDs. [9][10][11][12][13][14] One of those techniques is using a femtosecond laser for making capsulorhexis and for dividing the nucleus which was previously evaluated in a randomized controlled trial by Schargus et al 15 They found that femtosecond laser-assisted treatment without the use of OVD have no additional risk to the corneal endothelium. However, the use of femtosecond laser is an additional cost to the routine phacoemulsification.…”

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.
