RAPID technique was performed in 54 eyes of 54 patients (31 males and 23 females; mean age 46.35±3.95 years). The soft nucleus was emulsified, after performing hydrodissection, in a stepwise manner in the safe zone away from posterior capsule and corneal endothelium. Centurion/Infiniti Phacoemulsification system (Alcon Laboratories, Inc.) was used with vacuum parameters at 475 mm Hg and an aspiration flow rate of 0–45 mL/min in linear mode. The primary outcome measures were cumulative dissipated energy (CDE), ultrasound time (UST), amount of fluid used, surgical complications and mean endothelial cell loss.Results: Phacoemulsification with IOL implantation was performed successfully in all patients without any intraoperative complications. CDE was 1.03±0.61. Total UST for nuclear emulsification was 3.84±3.27 seconds and fluid used was 10±2.35 milliliters. Postoperative follow-up examinations were done on 1, 4, 14, 30 and 90 days. Mean percentage of endothelial cell loss was 7.05±2.65% (mean endothelial cell counts were 2383.75±105.21 cells/mm2 preoperatively and 2215.78±114.9 cells/mm2 3 months postoperatively).Conclusion: RAPID is an en masse non-fragmentation technique for purely soft cataracts. This technique requires neither any specialized instrumentations nor the use of high vacuum with complimenting surge preventing software. Simple stepwise multi-planer approach of RAPID technique allows easy and fast emulsification of soft cataracts with simultaneous safeguarding of posterior capsule and corneal endothelium.Keywords: soft cataract phacoemulsification, RAPID en masse phacoemulsification technique, soft cataractOm Parkash RMahajan SOm Parkash TVajpayee RBOm Parkash TDove Medical PressarticleSoft cataract phacoemulsificationRAPID en masse phacoemulsification techniquesoft non fragmentable cataract.OphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 755-762 (2019)
