Did Microcoaxial Mode Revolutionize Clear Corneal Cataract Surgery? Comparative Retrospective Study About 2000 Cases

Abstract

Purpose: : the authors report their experience in the clear corneal cataract surgery by phacoemulsification and compare their data between 1000 interventions realized in 2008 with corneal incision of 2.8mm and 1000 other interventions realized in 2010 with corneal incision of 2.2mm.

Methods: : the reported data contain besides the age and the sex of the patients, the duration of intervention, the power of the set up IOL, the rate of final suture, the type of used implants, the felt pains and the met complications. Devices used in the group 1 in 2008 (incision of 2.8mm) was the Millénium device of baush&lomb, and in the group 2 in 2010 (incision of 2.2mm) the Stellaris device of Bausch&lomb. The data of the first thousand patients operated in 2008 were compared with the data of the first thousand patients operated in 2010, all them being operated by the same surgeon.Results: in the groups 1 and 2 mean ages are comparable: 72.98 and 73.54, the ratio woman / man also: 584/416 and 583/417, as well as the percentage of interventions realized under topical anesthesia: 96.5 and 97.9 %. Mean duration of

Conclusions: : by comparing the various reported clinical data, the authors show through this study that the contribution of the microcoaxial surgery with 2.2mm incision with regard to "traditional" 2.8mm incision, rest enough little limited. The only variable concerns the rate of final suture, passing of 44.4 % in microcoaxial mode in 39.5 % in traditional mode. All other data: duration of intervention, felt pains and met complications are strictly comparable.
