“…More recently, the introduction of trifocal IOL models provide surgeons with additional options when considering appropriate IOL selection. Comparative literature highlights the extended reading range provided by the three separate focal points of the trifocal IOLs compared to multifocal IOLs, leading to greater optical independence for all distances [9, 12, 13]. Conversely, the presence of two out-of-focus images increases the likelihood of haloes compared to a single out-of-focus image [14].…”

BackgroundIndependence from all optical aids, and freedom from unwanted symptoms, following cataract and lens surgery remains the ultimate goal of both patient and surgeon. The development of trifocal IOL technology provides an ever-increasing range of options. The purpose of our study is to understand the predictability, safety and efficacy of a new trifocal intraocular lens (IOL) following cataract or refractive lens exchange (RLE) surgery.MethodsThis was a retrospective consecutive case series of patients undergoing cataract extraction or RLE followed by implantation of the Alcon IQ Panoptix IOL. Pre and postoperative refractive and visual parameters were recorded and evaluated. As the cohort followed a normal distribution, standard parametric tests were used. Paired t-test was used to compare the difference between target and postoperative refractive errors. The incidence of intraoperative and postoperative complications was also reported.ResultsThe IOL was implanted in 66 eyes of 33 patients. Mean postoperative spherical equivalent (SE) refraction was -0.08 ± 0.25 dioptres (D). This was not significantly different from the target refraction (p = 0.841). Sixty-five percent of patients were within ± 0.25 D of the target SE refraction with 100% within ± 0.50 D of intended correction. Mean postoperative uncorrected distance visual acuity (UDVA) was 0.01 ± 0.10 LogMAR. All patients achieved an unaided distance acuity of 20/40 or better postoperatively. Binocularly, 100% saw 0.20 LogMAR or better at near without correction and 88.9% achieved this level for uncorrected intermediate visual acuity. No intraoperative complications were noted. Five patients complained of moderate haloes in the early postoperative period.ConclusionThe AcrySof IQ Panoptix IOL provides functional uncorrected visual acuity at distance, intermediate and near positions. Our results remain equivalent with existing trifocal IOL outcomes and provide surgeons with a further IOL alternative for the patient motivated to obtain true spectacle independence. Surgeons should consider individual reading and working requirements when counselling patients preoperatively to optimise postoperative patient satisfaction.Electronic supplementary materialThe online version of this article (doi:10.1186/s40662-017-0076-8) contains supplementary material, which is available to authorized users.

“…The recent introduction of the trifocal IOL provides more options during the selection of the appropriate IOL. Comparative studies have demonstrated higher optical independence for all distances of the trifocal in comparison to the multifocal IOLs [9][10][11] . Many papers showed the better action of the multi and trifocal lens in visual and refractive results [10,[12][13][14] , but as patient satisfaction, there were little studies on outcome of trifocal lens on patients fulfillment, use of sight, besides patients 'performance of common daily activities, like reading or driving.…”

Introduction: Phacoemulsification is gaining popularity for cataract removal and refractive lens exchange, and the continued evolution of equipment, techniques and intraocular lens. Multifocal intraocular lens (IOL) design, has resulted in the evolution of postoperative goals to include not only visual restoration but to improve patient satisfaction as well as visual outcomes and quality of life. The aim is to evaluate visual and refractive results following implantation of a trifocal diffractive intraocular lens (IOL) and to determine patient satisfaction and glasses independence. This was a prospective study enrolling 74 eyes of 42 patients undergoing lens removal surgery with implantation of trifocal diffractive Medicontur IOL (Liberty). Visual and refractive outcomes were evaluated preoperatively and 6-month postoperatively. Patient satisfaction, spectacle use, photic phenomena presence, and ease of performance of vision-related activities were assessed via questionnaire. 74 patients included in this study entirely patients finished the 6-month after surgery. 77% were males and 23% females, 84% of them with age ≤ 30 years old and 16% > 30 years old mean range of age (45.04 ± 12.3) years (19-69 years). 99% of them with glare absent while 99% of patient with no eyes discomfort, (100%) did not require glasses for near or far vision postoperatively, This table show difference between visual acuity of patients after and before surgery (P-value< 0.05), so there is a difference between VA for near before and after surgery, there was difference between refraction after and before surgery (P-value< 0.05) and refraction in spherical is better after surgery. In conclusion, implantation of the Medicontur trifocal IOL (Liberty) after lens removal surgery restores visual acuity with a minimal level of photic phenomena, better to doing normal everyday actions with no glasses, and with good satisfaction of patients after operation.

“…[17] In our study, we used a surgeon-bent cystotome to fracture the nucleus prior to the phacoemulsification step; as there was no release of ultrasonic power throughout the process, the ultrasound power and EPT in the CAPPS group were much lower than those in the CPS group, which is consistent with previous, similar research. [18]…”

Background:This study aimed to investigate the safety and efficacy of the cystotome-assisted prechop phacoemulsification surgery (CAPPS) and conventional phacoemulsification surgery (CPS) in patients with IV degree nucleus cataract.Methods:The prospective, randomized, consecutive, comparative cohort study consecutively recruited Chinese age-related cataract patients, CAPPS and CPS were performed by a seasoned surgeon. Postoperative follow-up was at 1 day, 1 week, 1 month, 3 months, 6 months, and 1 year, and the outcome measures comprised ultrasound power, effective phacoemulsification time (EPT), corrected distance visual acuity (CDVA), endothelial cell density (ECD), corneal endothelium loss rate (ECL), central corneal thickness (CCT), and intraoperative and postoperative complications.Results:Patients in both groups gained a better CDVA postoperatively. The ultrasound power and EPT in the CAPPS group were lower than the CPS group (P < .001). ECD value decreased at each follow-up visit and did not return to the preoperative level; CPS resulted in greater endothelial cell loss than CAPPS did, which was significant. CCT increased immediately after the surgery, and decreased thereafter. The mean CCT values returned to preoperative levels at 3 months after surgery in the CAPPS group while it took 6 months in the CPS group. The differences in cornea edema and anterior chamber flare between the 2 groups were not significant at 1 day postoperatively (P = .070 and .094, respectively), while at the 1-week time point, the differences were statistically significant (P = .002 and .001, respectively).Conclusion:CAPPS appears to be an excellent method for treating hard nucleus cataract.
