“…This is an important method to assess and compare the satisfaction of subjects included in the four groups (17,18) . It is also in agreement with the idea that hyperopic patients would have milder symptoms than myopic patients, although this comparison was not done in this study (19) .There was no difference in spherical equivalent between study groups. The refractive outcome was very close to emmetropia, which was our goal.…”

Purpose: Development and validation of quality of life questionnaire in pseudophakic patients in Portuguese. Methods: The modified Cataract TyPESpecification questionnaire was specifically developed to assess quality of life after cataract surgery, functional status evaluated with 10 items and contains 18 questions. All questions were applied by a single examiner, with the goal of graduating visual satisfaction from 0 to 10 (0 means very dissatisfied, 5 neutral, 10 very satisfied).This prospective comparative study included 142 eyes of 71 patients in Sao Paulo University. The ophthalmologic evaluation performed included near, intermediate and distance corrected and uncorrected visual acuity and quality of life questionaire. The minimum follow-up was 6 months. Results: The mean age of patients was 60.7± 6.6 years in theTecnis ® MF, 63.1 ±4.4 years in-groupRestor ® 63.7±4.2 years in-group SN60AT/SN60WF. Uncorrected and distance-corrected near visual acuity were statistically higher in theRestor ® and Tecnis ® groups compared to the SN60AT/SN60WF group (p<0.001). There were no statistical differences between groups comparing uncorrected and best-corrected distance visual acuity (p=0.56). Satisfaction questionnaire showed high glasses independence fortheTecnis ® MF (9.3 /10) and Restor ® (8.7 /10) INTRODUCTIONP hacoemulsification and IOL implantation using increasingly smaller incisions have allowed rapid visual recovery with low rates of complications in the hands of experienced surgeons, as well as good quality of vision in the postoperative period. Assessment of the quality of vision can be done through various tests, such as those assessing contrast sensitivity, which is the ability to distinguish the details of images and depends on ambient brightness (1)(2)(3)(4) .In order to provide additional benefits to the visual quality of pseudophakic patients, intraocular lenses (IOLs) have been refined using an aspherical lens design to correct positive spherical aberrations of the cornea (5)(6)(7)(8) . One such aspherical lens is the SN60WF lens, developed from the SN60AT lens, both produced by Alcon Laboratories (Fort Worth, Texas, USA). The former provides greater reduction in spherical aberrations with better vision in low light conditions and increased contrast sensitivity in the postoperative period compared to the latter (5,6,9) .Monofocal IOLs are traditionally used for intraocular implants in cataract surgery. Do to their lack of optical correction, they do not provide a satisfactory depth of focus at varying distances. Despite the potential benefits of multifocal IOLs, their indications are still limited (10,11) .More advanced multifocal IOLs aim to provide contrast sensitivity similar that accepted for monofocal IOLs and to induce minimal optical aberrations. However, the scientific literature reports a loss of contrast sensitivity and functional vision associated with photic phenomena that affect patient satisfaction (12,13) .The aim of this study was to develop and evaluate a quality of life qu...

“…Steinert et al [1] reported that the focal depth of eyes with the AMO Array multifocal IOL was 1.00 dpt wider than that of eyes with monofocal IOLs 1 year postoperatively. Bellucci and Giardini [2] compared the 3M diffractive multifocal IOLs with monofocal IOLs and concluded that the average accommodative ability of multifocal IOL was 2- to 3-fold greater than that of monofocal IOLs. Weghaupt et al [3] suggested that 3.00–4.00 dpt focal depth were ideal without decreasing the whole range.…”

Purpose: To evaluate the efficacy, safety and early visual quality of the AcrySof ReSTOR multifocal intraocular lens (IOL) following cataract surgery. Setting: Eye Center of Shandong University of Traditional Chinese Medicine, Jinan Shierming Eye Hospital, Jinan, Shandong, China. Methods:After small-incision phacoemulsification, AcrySof ReSTOR IOLs were implanted in 20 subjects (40 eyes, ReSTOR group). Monofocal IOLs were implanted in 18 subjects (36 eyes, control group). Three to six months following bilateral implantation, visual acuity, depth of focus, corneal astigmatism, contrast sensitivity, glare sensitivity, visual field and spherical aberration were compared between the groups. A subjective outcome questionnaire was also completed by the subjects. Results: Uncorrected near visual acuity 0.5 or better was achieved by 92.5% of the ReSTOR eyes. In the monofocal eyes, only 33.3% of the eyes achieved uncorrected near visual acuity of 0.5 or better. There was no statistical difference between corrected near, distance visual acuity, and uncorrected distance visual acuity in the 2 groups (p > 0.05). In patients with visual acuity 0.5 or better, the depth of focus was 4.87 ± 1.09 and 2.08 ± 0.69 dpt in the ReSTOR and control groups, respectively. The contrast sensitivity, glare sensitivity and visual field of both groups were similar (p > 0.05). The spherical aberration of the 2 groups was similar (t = –0.37, p = 0.71). Visual disturbances were minimal with only 1 patient in each group complaining of glare at night. Conclusion:The AcrySof ReSTOR multifocal IOL is a safe and effective treatment for cataracts.

“…The introduction of refractive and diffractive multifocal IOLs provides only a partial solution as these IOLs are associated with a high incidence of side effects such as halos, flare, glare, and reduced visual acuity and contrast sensitivity. [15][16][17] Thus, accommodating IOLs that can focus on objects at different distances by an anterior shift of the optic caused by ciliary muscle contraction have been recently proposed. [18][19][20][21] There is considerable current research of the measurement of accommodative changes in refracting power and of objective methods that can demonstrate biometric changes in the eye.…”
