The objective of this paper is to study the incidence of cystoid macular edema (CME) using optical coherence tomography (OCT) following uneventful small incision cataract surgery (SICS) and phacoemulsification. Topical anaesthesia may be sufficient for phacoemulsification in expert hands. PDF Clinical & Experimental Radwan J Clinic Experiment ... Purpose: To Compare the central macular thickness after SICS and Phacoemulsification cataract surgery using OCT. Methods: It was a study to compare the Central Macular thickness after SICS and Phacoemulsification cataract surgeries performed at Sankara Eye Hospital, Ludhiana. Typically, the energy lost by SiC during the reverse recovery phase is just 1% of the energy lost by silicon. Advantages of Silicon (Si) | disadvantages of Silicon (Si) Postoperative congestion is minimal after phacoemulsification, as phaco is usually performed through a clear corneal incision. How to Perform Manual Small-Incision Cataract Surgery ... Description Phacoemulsification is a variation of extracapsular cataract extraction , a procedure in which the lens and the front portion of the capsule are removed.Formerly the most popular cataract surgery, the older method of extracapsular extraction involves a longer incision, about 0.4 in (10 mm), or almost half of the eye. Disadvantage: As the bore is large, it cannot be used in SICS and Phacoemulsification without enlarging the side ports. Quick Summary Laser-assisted cataract surgery is an impressive technology that produces precise results. 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. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the anterior chamber . Small incision. Meeting the organization's requirements, which ensures compliance with regulations and provision of products and . Just as with SiC, there are many inherent challenges that must be All patients were operated by the same surgeon with more than 5 years' experience. Surgical speed and efficiency are paramount in the developing world because cataract surgical capacity is limited by the severe shortage of ophthalmic surgeons. 2, 3 It may be advisable to perform extracapsular cataract extraction (ECCE), rather than phacoemulsification or manual small incision cataract surgery (SICS). Five patients originally posted for phacoemulsification had to convert to SICS due to operative difficulties. phacoemulsification reducing the risks associated with peribulbar injection. Background. We offer 4 weeks short-term specially designed unique stepwise training program in SICS & Phacoemulsification. This led to the advent of a sutureless technique: MSICS, which has been shown to give results comparable to phaco in terms of rapid visual rehabilitation. This, in turn, has a number of implications for system complexity and cost.

Ultrasonic Phaco helps break up the cloudy lens. The excellent thermal conductivity of silicon carbide MOSFETs allows for better thermal conductivity and lower switching losses. In small incision cataract surgery (SICS) the most common incision taken is the superior one than temporal site, which is farthest from the visual axis and less likely to affect corneal curvature. People in the phacoemulsification group were also more likely to achieve BCVA of 6/12 or more at three months (RR 1.12, 95% CI 1.03 to 1.22, four studies, 645 participants) and one year (RR 1.06, 95% CI 0.99 to 1.14, one study, 439 participants), but the difference between the two groups was smaller. 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 Surgical time was shorter for SICS than phacoemulsification (P< .0001) Compared to traditional ECCE, MSICS has the advantage of a self-sealing sutureless wound. The reduced switching losses alone (even at high voltages) mean far less heat generation, thus reducing the thermal management requirements of systems using silicon carbide MOSFETs as opposed to silicon IGBTs. Short Term Intensive Phaco Course: The short term course allows the trainee to observe and perform about 30 procedures, under the supervision and guidance of the clinic surgeons over a period of 15 - 20 days.While the trainee will observe and perform the procedure, the experienced consultant . In view of the previous findings, the study aimed to compare Phacoemulsification is used by most surgeons in developed countries and enables the most elegant surgery but at a high cost. Long Term SICS and Phaco Training is for 3 months. Participants: Four hundred eyes of 400 patients, 1:1 randomization with half in each arm of the trial. Benefits of a documented quality management system include: Meeting the customer's requirements, which helps to instill confidence in the organization, in turn leading to more customers, more sales, and more repeat business. Use: Manual aspiration of the lens cortex. Phaco needs more technical expertise and is a costly modality for the common mass, whereas SICS is an inexpensive alternative with comparable visual outcome. Mean . -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. Better safety, efficiency However, the larger incision used still induces greater astigmatism than phacoemulsification. Too much ultrasound energy can prolong healing and potentially damage the cornea. The MICS technique had advantages over the small-incision cataract surgery (SICS) technique in minimizing the destructive effect of the large incision size on the optical quality of the cornea . In resource poor settings MSICS also has several distinct advantages over phacoemulsification .
