Dr. Purpose: To compare preoperative and postoperative values of best corrected visual acuity (BCVA), foveal and perifoveal thicknesses changes in patients undergone phacoemulsification+intraocular lens(PHACO+IOL) surgery, PHACO+IOL+anterior vitrectomy surgery and extracapsular cataract extraction(ECCE)+IOL surgery.
Material and Methods: 123 patients undergone cataract surgery between June 2009-July 2010 were evaluated and divided into three groups according to the type of cataract surgery. Group 1, group 2, and group 3 were composed of 48 PHACO+IOL, 42 PHACO+IOL+anterior vitrectomy, and 33 ECCE+IOL patients respectively. For all patients preoperative and postoperative 1st week, 2st month, 3rd month, 6th month BCVA, optic coherence tomography (OCT), foveal and perifoval thicknesses were noted.
Results: Increase in the BCVA was statistically significant in the all three groups in the 1st week, 1st month, 3rd month, and 6th month after surgery (p<0.001). Postoperative foveal and perifoveal thicknesses were increased in the all three groups in the 1st week and this was statistically significant (p<0.001). In group 1 and group 3, foveal and perifoveal macular thicknesses was gradually decreased in the 1st, 3rd and 6th month postoperatively and with compared to preoperative values there was no statistically significant difference (p>0.05). In the group 2, there was statistically significant increase in macular thicknesses in the 1st and 3rd months after surgery (p<0.001). In group 2, in the 6th month, macula was thicker than preoperative values and this was not statistically significant (p>0.05).
Conclusion: Macular edema could take place after all cataract surgeries especially when posterior capsular was torn. OCT seems to be useful method for diagnosis and monitoring of macular edema. Keywords : Cataract surgery, macular thickness, optic coherence tomography
