Comparison of postoperative parameters in cataract surgery with two different fluidic settings

INTERVENTION: Participants will be randomised to receive either low‐ or standard fluidic settings. They will all be implanted with an AcrySof SN60WF intraocular lens (IOL). Perioperatively the saline bag will be weighed before and after surgery to measure the amount of saline used. The saline for hydrodissection and wetting of the cornea is withdrawn before the first weight is measured. The Cumulative Dissipated Energy will be recorded as well as the surgery time. All operations will be videotaped with phacomachine lay over so that the energy used is shown at the end of surgery. Patients will have a preoperative check, follow‐up 1 day, 3 weeks and 3 months after surgery. CONDITION: Postoperative complications in cataract surgery ; Eye Diseases ; Postoperative complications in cataract surgery PRIMARY OUTCOME: 1. Duration of surgery is measured during surgery in minutes; 2. Consumed balanced saline solution is determined by weighing the saline bag before and after surgery. The saline for hydrodissection and wetting of the cornea is withdrawn before the baseline measurement.; 3. Cumulative dissipated energy is determined by recording the CDE‐value from the LCD display of the Phacoemulsification machine; 4. Central corneal thickness is measured with Anterior segment OCT at baseline, 1 day, 3 weeks and 3 months; 5. Endothelial cell density is measured using confocal microscopy at baseline and 3 months; 6. Anterior chamber flare is measured by laser flare meter at baseline, 1 day, and 3 weeks; 7. Macular thickness is measured by OCT at baseline, 1 day, 3 weeks and 3 months SECONDARY OUTCOME: 1. Intraocular pressure is measured using Goldmann applanation tonometry at baseline, 1 day, 3 weeks and 3 months; 2. Corrected distance visual acuity is measured using a ETDRS chart during ophthalmologic examinations at baseline, 1 day, 3 weeks and 3 months INCLUSION CRITERIA: 1. Aged between 55 and 85 2. Presence of senile cataract
