Abstract


PURPOSE: To assess the effect of uncomplicated cataract surgery on central macular thickness assessed with Optical
coherence tomography.
METHOD: Our study was a Prospective non interventional observational study. In this study 100 eyes of 100 patients
were assessed by optical coherence tomography preoperatively and postoperatively at day 1day, 14 day, 28 day after
uncomplicated cataract surgery with Posterior Chamber Intraocular Lens (PCIOL) implantation under peribulbar
anesthesia. The study included 50 eyes of 50 patients undergoing uncomplicated manual small incision cataract surgery
(Group1) and 50 eyes of 50 patients undergoing uncomplicated phacoemulsification cataract surgery (Group 2).Among
each group 30 eyes of 30 patients were started postoperatively on topical NSAIDs. Eyes with diseases predisposing them
for postoperative macular edema, eyes with preexisting macular edema were excluded. The preoperative and post
operative day1, day14, day28 changes in subfoveal,parafoveal and perifoveal thickness of macula on OCT of each group
were noted .
RESULTS: The pre operative mean subfoveal thickness, mean parafoveal thickness, mean perifoveal thickness in
patients undergoing MSICS with PCIOL( Group 1) and PHACO with PCIOL (Group 2) were 242.08± 11.68 μm, 309.66±
17.88 μm, 269.84± 14.57 μm and 241.88± 14.35 μm, 317.30± 26.16 μm, 267.98± 17.25 μm respectively.
At day 14, postoperative mean subfoveal thickness, mean parafoveal thickness, mean perifoveal thickness in patients
undergoing MSICS with PCIOL with and without postoperative NSAIDS were 260.16± 14.76 μm, 328.03± 17.14 μm,
284.13± 20.71 μm and 275.15± 13.43 μm, 335.55± 20.19 μm, 311.25± 69.09 μm respectively.
At day 28, postoperative mean subfoveal thickness,mean parafoveal thickness, mean perifoveal thickness in patients
undergoing MSICS with PCIOL with and without postoperative NSAIDS were 245.16± 13.60 μm, 308.20± 16.05 μm,
269.73± 20.76 μm and 252.85± 12.07 μm, 319.50± 21.19 μm, 285.80± 50.53 μm respectively.
At day 14, postoperative mean subfoveal thickness,mean parafoveal thickness, mean perifoveal thickness in patients
undergoing PHACO with PCIOL with and without postoperative NSAIDS were 247.36± 13.63 μm, 310.13± 25.71 μm,
262.26± 18.14 μm and 248.75± 15.33 μm, 332.25± 25.90 μm, 290.60± 78.37 μm respectively.
At day 28, postoperative mean subfoveal thickness, mean parafoveal thickness, mean perifoveal thickness in patients
undergoing PHACO with PCIOL with postoperative NSAIDS were 238.76± 14.16 μm, 300.06± 27.58 μm, 252.30± 16.79
μm and 242.45± 16.76 μm, 325.70± 25.54 μm, 283.05± 70.33 μm respectively.
Also Phaco energy linearly co relates with postoperative macular thickness, mean subfoveal macular thickness,
parafoveal macular thickness, perifoveal macular thickness on postoperative day 14, post operative day 28 is satistically
significant high in those patients in whom more phaco energy is used.
