[Patient's pain feeling and surgeon's comfort--ECCE versus phacoemulsification].

PURPOSE: To compare patient's pain and surgeon's comfort during ECCE performed under retrobulbar anesthesia and phacoemulsification under topical anesthesia. MATERIAL AND METHODS: 120 patients scheduled for planned routine cataract extraction were divided in 2 groups: group 1-60 eyes, ECCE under retrobulbar anesthesia and group II-60 eyes, phacoemulsification under topical anesthesia. Immediately after operation patients were asked, to answer questions about their feeling during surgery. Simultaneously, the surgeon filled up the questionnaire, concerning patients behavior during the entire procedure. RESULTS: Statistically significant higher level of pain was reported in group I (ECCE). The most painful moment of the procedure was retrobulbar injection. During surgery pain feeling in both groups was similar. Both types of anesthesia provided very good level of surgeon's comfort. The longer operation, the higher level of pain and lower surgeon's comfort were reported in both groups. CONCLUSIONS: Patients having ECCE performed under retrobulbar anesthesia reported more pain comparing to phacoemulsification under topical anesthesia. Both anesthesia methods provided high level of surgeon's comfort.

[Cataract phacoemulsification techniques: "divide and conquer" versus "stop and chop"--comparative evaluation of operation course and early results].

PURPOSE: To compare ultrasound time, quality and quantity of intraoperative complications together with the eye condition in early postoperative period in patients who underwent "divide and conquer" and "stop and chop" cataract phacoemulsification. MATERIAL AND METHODS: "Divide and conquer" phacoemulsification was performed in 49 eyes, whereas "stop and chop" technique in 67 eyes. Before surgery axial lengths of the eye, anterior chamber depth and pupillary reflex were measured. During the surgery effective phaco time, nucleus hardness and all the complications were recorded, whereas in the first day post operation visual acuity and amount of corneal edema were examined. RESULTS: The ultrasound time was significantly shorter in patients operated with "stop and chop" technique. In the first postoperative day better visual acuity and smaller amount of corneal edema were observed in this group. CONCLUSIONS: "Stop and chop" technique gives better early postoperative results in comparison to "divide and conquer" technique. The number of intraoperative complications in both group is low.
