“…Increasingly, attention is being devoted to measuring VRQoL, and interest in outcomes research has grown from a recognition that patients are more interested in how interventions affect their well-being than in improvements in visual acuity [16]. The good news is that many studies have confirmed that VRQoL of patients with cataracts significantly improved after Ph-IOL [17][18][19][20][21]. In the present study, we also confirmed that after Ph-IOL, both visual acuity and utility value increased significantly.…”

Purpose To observe the long-term changes in dry eye symptoms and vision-related quality of life in agerelated cataract patients after phacoemulsification. Methods A total of 101 cataract patients after phacoemulsification combined with IOL implantation (Ph-IOL) in one eye were enrolled. Visual acuity, tear film breakup time (BUT), and Schirmer test 1 (ST1) were measured before and 1, 3, and 6 months after surgery. Ocular Surface Disease Index (OSDI) scores were used to evaluate the severity of dry eye symptoms. Utility values were assessed by the time trade-off (TTO), standard gamble for death (SGD), standard gamble for blindness (SGB) and rating scale (RS). Results The average LogMAR visual acuity in the operated eye was 1.35 ± 0.50 and increased rapidly after Ph-IOL, approaching a peak at 3 months (0.26 ± 0.15). The BUT and ST1 results decreased abruptly 1 month after surgery and gradually recovered until 6 months. OSDI scores increased significantly after surgery and gradually decreased until 6 months. Utility values evaluated by TTO, SGD, SGB and RS before surgery were 0.67 ± 0.19, 0.75 ± 0.15, 0.67 ± 0.20 and 0.2 ± 0.18, respectively, and increased to 0.91 ± 0.06, 0.98 ± 0.04, 0.92 ± 0.52 and 0.91 ± 0.06, 6 months after. Utility values measured with TTO, SGB or RS correlated significantly (P \ 0.05) with visual acuity and OSDI scores pre-and postoperatively. Conclusions Dry eye symptoms persist more than 3 months after Ph-IOL. Utility values were negatively influenced by dry eye symptoms.

“…Accurate determination of ocular dominance is useful in clinical decision-making, as it relates to monovision management of presbyopia [37][38][39] with intraocular lens implant in cataract surgery, 40,41 contact lenses, 39,42 or LASIK. 43,44 The determination of ocular dominance has mainly been based on sighting dominance, which takes little time to perform.…”

PURPOSE. To quantify ocular sensory dominance and investigate its relationship to stereopsis. METHOD.A total of 69 subjects participated in the study. Ocular dominance was measured by a continuous flashing technique, with the tested eye viewing a Gabor patch increasing in contrast, and the fellow eye viewing a Mondrian noise decreasing in contrast. In each trial, the log ratio of Mondrian to Gabor's contrasts was recorded as a subject first detected the Gabor. We collected 50 trials for each eye and an interocular difference was analyzed with a rank-sum test. The z-value was used as the ocular dominance index (ODI) to quantify the degree of ocular dominance. A subject with ODI ‡ 2 was categorized as having a clear ocular dominance, and a subject with ODI < 2 was considered as having balanced eyes (unclear dominance). The stereoacuity was measured with random dot patterns with durations varying from 50 to 1000 ms. The best achievable stereoacuity (D min ) and the integration time needed to acquire that (T min ) were calculated. RESULTS.A total of 30 subjects had balanced eyes and 39 had clear ocular dominance. T min was significantly longer in subjects with clear ocular dominance than in subjects with balanced eyes (180.18 vs. 121.17 ms, P < 0.01). T min was positively correlated with ODI (P < 0.01). However, D min in subjects with clear dominance was not different from that in subjects with balanced eyes (40.60 vs. 35.73 arcsec, P ¼ 0.18).CONCLUSIONS. Ocular dominance is not associated with how fine the stereoacuity is, but rather how quickly the best stereoacuity is acquired.

“…PDGF is a cell factor that can promote mesenchymal proliferation and division, and is derived from mesenchymal tissue such as fibroblasts, epithelial cells, and endothelial cells. PDGF functions by combining with its cell surface receptor PDGFR (Arshinoff and Bastianelli, 2011; Mancino et al, 2011;Zhang et al, 2011). It has different subtypes such as A, B, C, D, etc.…”
