advantages of phacoemulsification over sics

A comparative study on oblique stab incision sics and ... This was a descriptive, prospective study where 200 patients undergoing cataract surgery were randomly divided into two groups over a period of 1 year. Phacoemulsification for Cataracts - procedure, recovery ... Background. The Undeniable Advantages of SiC Technology Over Si - EBV ... Many eye surgeons who were early, enthusiastic adopters of laser-assisted cataract surgery have now gone back to manual cataract surgery. Phacoemulsification cataract surgery has a smaller incision of 3mm. Microincision Cataract Surgery - Medscape One very vital aspect of learning Phaco in four weeks is that you need to be an ECCE surgeon who is in touch with surgery. Meta-analysis to compare the safety and efficacy of manual ... Log in. For instance, out of the 4,966 cataract treatment claims raised by public hospitals, 77% adopted SICS technique. Additionally, SiC has a thermal conductivity more than three times better than Si, enabling the use of smaller die for the same temperature rise. Outcomes of manual SICS have been reported in numerous studies, including several from the Aravind Eye Hospital.6, 7 However, studies have directly compared the outcomes and safety of manual SICS and phacoemulsification, and these had small study populations.8, 9 We therefore sought to retrospectively analyze these 2 procedures with respect to . After creation of a superior incision and filling of the anterior chamber with a viscoelastic substance, continuous curvilinear capsulorhexis was performed with a capsulotomy needle or a capsulotomy forcep. Compared to traditional ECCE, MSICS has the advantage of a self-sealing sutureless wound. Five patients originally posted for phacoemulsification had to convert to SICS due to operative difficulties. Another advantage of manual SICS over other methods of cataract surgery is the shorter duration taken, The data can be used for various types of research. An SiC die needs specially designed packaging and gate drivers to reap the advantages. However, the larger incision used still induces greater astigmatism than phacoemulsification. The crack and flip phacoemulsification technique combines the advantages of circumferential division. Cystoid Macular oedema - This is swelling in the retina and can occur in 1- 5% of patients following cataract surgery. The benefits compared to silicon are marginal at or below 600V. 3. Mean . Materials and Methods: A Study sample of 100 patients were included. All trainee surgeons will be certified after successful completion of the course. 4 The most significant advantage of manual SICS over phacoemulsification was that it proved to be a much faster and cost-effective surgical technique in eyes with an advanced white cataract. Topical anaesthesia may be sufficient for phacoemulsification in expert hands. He also stressed that no side port incision is required, surgeons can obtain the benefits of small self-sealing incision without the added cost of phaco. Unlike phacoemulsification, MSICS is a low-cost surgical procedure that does not require expensive equipment. Advantages of Cross-Sectional Study Not costly to perform and does not require a lot of time. Some patients may get bruising around the eyelids in the days following surgery. It has the advantages compared to ECCE of a smaller, self-sealing, suture-less wound, and the advantages over phacoemulsification of lower cost and less need for technology. A time table will be provided to the trainee about his schedule. 6-8,10,11 In our sample, 38.1% of all patients achieved a BCVA of 20/40, which improved to 61.5% when those with preexisting ocular pathologies were . Cataract surgery has undergone many changes with the size of incision progressively decreasing over time with an incision of 12.0 mm for intracapsular cataract extraction to 2.2-2.8 mm in phacoemulsification. This leads to blurred vision. Ciputra SMG Eye Clinic uses The New CENTURION Vision System technology, which is the only sophisticated Phaco machine. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the anterior chamber . Surgical speed and efficiency are paramount in the developing world because cataract surgical capacity is limited by the severe shortage of ophthalmic surgeons. Phacoemulsification surgery was performed in all eyes under peribulbar/posterior subtenon anesthesia by 3 experienced surgeons. The reason is simple: GaN offers more than just low noise. Its advantages over traditional ECCE and phacoemulsification include reduced cost, operating time, and post-operative corneal edema, a self-sealing scleral incision, and the need for less technology and equipment. In contrast to a two-level converter with a 1,200-V SiC or IGBT, GaN (as shown in Figure 4) has some advantages in multilevel converter applications, including: • Superior switching figures of merit (FOMs). Benefits or advantages of Silicon (Si) Following are the benefits or advantages of Silicon (Si): As mentioned, it is second most abundant element available in the crust of the Earth. In the context of the debate on SICS vs Phaco, a greater poor visual outcome (<6/60) for Phaco (6% of patients) compared to SICS (1% of patients) was recorded in a Nepal study in 2009 (13). The excellent thermal conductivity of silicon carbide MOSFETs allows for better thermal conductivity and lower switching losses. 2, 3 It may be advisable to perform extracapsular cataract extraction (ECCE), rather than phacoemulsification or manual small incision cataract surgery (SICS). In SICS, however, the surgical skill and experience of the surgeon play a significant role in the results. Contains multiple variables at the time of the data snapshot. Trainee has to work in hospital from 8.30 am to 4.30 pm. As described earlier, GaN offers advantages over SiC in terms of reverse recovery, switching energy and speed, and dead-time losses. You may opt for advanced Phaco training as well. SiC and GaN also provide efficiency improvements over Si by having higher maximum operating temperatures, limiting device stress. Small incision. Future Direction Modern cataract surgery is extremely safe and efficacious, and we continue to push for advancements to improve outcomes and patient satisfaction. Manual SICS is the first choice alternative to phacoemulsification as it retains most of the advantages of "phaco" giving comparable visual results at a lower cost. (SICS) - the first choice alternative to phacoemulsification- retains most of the advantages of "phaco" giving visual results equivalent to phacoemulsification at lower cost. Phaco also requires longer training and, thus, more experienced and better paid surgeons. This type of bruising resolves over a few days. Although it's a relatively new technique, MSICS is . Numerous randomized controlled clinical trials have proved both techniques to be safe and effective for rehabilitating the vision of cataract patients.2-4 The advantages of both techniques are sutureless, require small incisions, and result in faster visual rehabilitation. Twenty patients with the pupillary size of at least 7 mm underwent clear corneal phaco while 27 patients with smaller pupils underwent SICS. -Phacoemulsification is a technique which employs the ultrasound energy and fluid dynamics to facilitate the removal of nucleus and cortex of the lens in the cataract surgery. It is a high volume surgery learned by surgeons in a short span of time. Richard Gianetti in 1996 reaffirmed that the nucleus capture is an inexpensive, phacoless, repeatable and relatively easy method of performing tunnel incision cataract surgery. This shows a fundamental cost savings for the OEM and the consumer, all while lowering emissions for the planet. Just as with SiC, there are many inherent challenges that must be Since 1986, 1 Manual small incision cataract surgery (SICS) offers better outcomes than ECCE and provides results equally as good as phacoemulsification ('phaco'), while being faster, cheaper, and less . SICS, a realistic solution. Phaco Versus Small Incision Cataract Surgery (SICS) Health Economic Study The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Phaco / ECCE / SICS Surgery. Because SiC tolerates higher voltages, power systems built on silicon carbide semiconductors require fewer switches in series. Advantage: Aspiration of the cortical matter is controlled. SICS like phacoemulsification is associated with rapid visual recovery, Cloudiness develops as a result of a buildup of protein in the lens, manual small-incision cataract surgery (SICS), and diminished vision even with an updated pair of glasses or contact lenses. There is huge market for crystalline Silicon (Si). Learn more about the advantages of Infineon's CoolSiCTM technology. Power semiconductors made from silicon carbide are capable of withstanding voltages up to 10 times higher than ordinary silicon. Those who opted for polymethylmethacrylate (PMMA) lenses underwent SICS. The mean surgically induced astigmatic change is 1.75 diopters (D) following a superior surgical approach while, 0.75 D of astigmatism is induced . ; MSICS rehabilitation is quicker with shorter healing times due to the lack of suture-related issues. posterior capsule opacification; phacoemulsification; extracapsular cataract extraction; In recent years there has been a pronounced increase in the use of phacoemulsification for cataract surgery, such that it is now the method of choice in North America, and a similar shift is occurring in the UK.1 This technique has a number of advantages over conventional extracapsular cataract extraction . Phacoemulsification In phacoemulsification, the surgeon uses an ultra-sound probe inserted through the incision to break up the nucleus of the lens into smaller pieces. Merits of phacoemulsification over manual SICS 1. Quick Summary Laser-assisted cataract surgery is an impressive technology that produces precise results. In a comparative study, both SICS and phacoemulsification were shown to achieve excellent visual outcomes (3). Outcomes using small incision 'non-phaco' techniques have been encouraging in settings where large volumes of surgery have been undertaken. In resource poor settings MSICS also has several distinct advantages over phacoemulsification . With the use of an operating microscope, the surgeon makes a very small incision about 3mm wide in the surface of the eye in or near the cornea. The newer technique offers the advantages of a smaller incision than standard ECCE, fewer or no stitches to close the incision, and a shorter recovery time for the patient. Over a 300,000-mile (10-year) lifetime of an EV, a SiC-driven OBC is anticipated to save approximately $435 when including efficiency savings, CO 2 savings, and system cost savings. We offer 4 weeks short-term specially designed unique stepwise training program in SICS & Phacoemulsification. It has a dual function of irrigation and aspiration. This, in turn, has a number of implications for system complexity and cost. Visual outcomes achieved with SICS are comparable to those of phacoemulsification, 19 with 71.0%-95.2% of all patients undergoing resident-performed SICS achieving a BCVA of 20/40 or better. Phacoemulsification -Phacoemulsification was invented and developed by Dr. Charles D Kelman in 1967. A sample size of 80 patients having cataract, age 41 to 70 years was included in this study.
