HERNANDEZ SILVA, Juan Raúl et al. Effectiveness of the intraocular lens ACRI SMART 46-S in micro-incision cataract surgery. Rev Cubana Oftalmol [online]. 2007, vol.20, n.2, pp. 0-0. ISSN 1561-3070.

Improvement and application of an industry devoted to modernize intraocular lenses and surgical tools have prompted a set of advances that allow optimizing, correcting and refining the surgical techniques for cataract surgery, particularly phacoemulsification. The most important aspect in this chain of advacements is aimed at reducing the surgical incision size in order to avoid a significant number of complications that are relatively frequent when using conventional extracapsular and intracapsular surgeries with over 10mm incisions. At present, new surgical techniques such as microincision cataract surgery have been developed. A retrospective and descriptive study was performed in 27 patients (eyes) diagnosed with pre-senile and senile cataract, who were surgically treated with microincision phacoemulsification and received the implant of an ACRi Smart 46.S 11 x 6mm acrylic intraocular lens in the posterior chamber at the Ocular Microsurgery Center of “Ramón Pando Ferrer” Ophthalmology Institute in the period from January 2004 to January 2005. It was found that most of cases were older than 50 years; the best corrected visual acuity recovered significantly in the postoperative period and induced astigmatism was low. Regarding the used phacodynamic parameters, the ultrasound power was generally low. There were few complications, being vitreous detachment secondary to break in the posterior capsule. It was concluded that microincision cataract surgery with Acri Smart 46 S lens implant is a valid, safe and effective choice of catract treatment that will allow developing in the future materials and technologies which would open up new paths for eye surgery, and also the use of optimal phacodynamic parameters would lead to a low number of complications.
