Microcoaxial cataract surgery outcomes: Comparison of 1.8 mm system and 2.2 mm system

Abstract

Both systems were safe and effective in microcoaxial phacoemulsification. The 1.8 mm system performed better with cortical-type cataract and the 2.2 mm system, with high-density nuclear-type cataract.

Microincision versus small-incision coaxial cataract surgery using different power modes for hard nuclear cataract

“…However, Lee et al 19 reported that the system was as safe and effective as the Intrepid Infiniti system in MICS. Thus, the results for the 2.75 mm incision would likely be similar between the 2 systems.…”

“…Lee et al 19 compared the Stellaris system (1.80 mm group) and the Intrepid Infiniti system (2.20 mm group) and found both to be safe and effective in microcoaxial phacoemulsification. For high-density cataract, they found a greater change between the initial incision size and the incision size after phacoemulsification, a longer phaco time, a greater mean CDE, and greater corneal endothelial cell loss in the 1.80 mm group.…”

Accuracy of toric intraocular lens implantation in cataract and refractive surgery

“…[27][28][29] Pseudophakic IOLs may be implanted through a 2.2 mm sutureless corneal incision, which has been shown to induce 0.24 to 0.52 D of flattening at the incised meridian. [30][31][32] When performing the toric pseudophakic IOL power calculation, we incorporated an incision-induced astigmatism of 0.50 D into the IOL power calculation. Toric pIOLs, however, require a much larger incision.…”

Comparison of phaco-chop, divide-and-conquer, and stop-and-chop phaco techniques in microincision coaxial cataract surgery

“…1 Coaxial microincision cataract surgery (MICS) has become a safe and effective technique for performing the procedure. 1 Endothelial cell loss was initially increased in MICS, especially in eyes with increased nuclear density, because of increased cumulative dissipated energy (CDE), aspiration time, and volume of balanced salt solution used. 2 The intraoperative energy used and ocular damage can be decreased in MICS with the pulse and burst modes compared with the continuous mode for hard cataract.…”
