RESUMO
@#OBJECTIVE: To compare the visual, refractive, and patient-reported outcomes of eyes implanted with one of 3 trifocal intraocular lenses (IOLs). METHODS: This is a cross-sectional, comparative, non-interventional study wherein subjects implanted with FineVision Micro F, AT LISA tri 839MP or AcrySof IQ PanOptix trifocal IOL after phacoemulsification were recruited. Manifest refraction, uncorrected and corrected visual acuity (VA) at distance, intermediate and near vision, contrast sensitivity, modulated transfer function (MTF) values and questionnaire answers were compared among the 3 groups using analysis of variance (ANOVA). RESULTS: Fifty-seven (57) eyes were included in the study: 21 eyes with FineVision (group A), 21 eyes with LISA tri (group B), and 15 eyes with PanOptix IOL (group C). The post-operative mean manifest spherical equivalent was -0.01D, -0.07D, and 0.05D, respectively (p=0.083). Uncorrected distance VA and best-corrected distance VA were similar among the groups. Groups A and C had better uncorrected and corrected intermediate VA at 80 cm and at 60 cm compared to group B. Group A had significantly better uncorrected near visual acuity than groups B and C (p=0.032). Mesopic contrast sensitivity testing showed group C had higher contrast sensitivities without glare in at the spatial frequency of 6 CPD (p=0.038) and with glare at 3 CPD (p=0.039) and at 12 CPD (p=0.009). MTF average height analysis showed that the group A had significantly superior resolution in far targets compared to groups B and C (p=0.001). At near targets, groups A and C had better resolutions compared to group B (p=0.017). There was no significant difference in patient satisfaction for far, intermediate and near VA among the groups. CONCLUSION: Eyes implanted with any of the 3 trifocal IOL designs achieved excellent uncorrected and bestcorrected distance, intermediate and near vision. FineVision and PanOptix provided significantly better intermediate vision than LISA tri at both 80 cm and 60 cm testing distance. FineVision had better near visual outcomes than PanOptix and LISA tri. Patient satisfaction was high in all 3 trifocal IOLS

Background: The hard palate is important for feeding, mastication and speech. Mammals with a defective hardpalate may die shortly after birth due to the inability to suckle. The interaction between tongue and hard palateis essential in the formation of certain speech sounds. In high arched palate, a proper palate-lingual contact isnot achieved, resulting in defective articulation. Surgically, the anatomy of hard palate can be modified by usingPalatal Height Index measurement, which could lead to the improvisation of palato-lingual contact andarticulation. This study aims to determine the Palatal height index.Results: After taking detail history of the subjects, the qualitative and quantitative parameters were measuredand then compared between the normal group (n=60) and high arched palate group (n=60) to know the statisticalsignificance between the two groups. The qualitative parameters measured in this study were shape of hardpalate, permanent dentition, microdontia, spacing of teeth, missing of teeth, eruption time of teeth, crowding ofteeth, malalignment, and malocclusion. The quantitative parameters measured in this study were average linearwidth, average height and palatal height index. Impressions of hard palate were taken through the prepared cast.From the prepared cast average linear width, average height and palatine height index were measured. The mean± SD value of average linear width measured between two molars was found to be 3.82 ± 0.32 in normal and 3.46± 0.17 in high arched palate subjects. The mean ± SD value of average height measured between two molars was1.58 ± 0.26 in normal and 2.06 ± 0.2 in high arched palate subjects. The mean ± SD value of palatine height indexmeasured between two molars was 41.98 ± 9.82 in normal and 59.69 ± 5.81 in high arched palate subjects.Conclusion: Palatal height index was high in the study group when compared to the normal group of similar agedcandidates and the results were found to be statistically significant. Crowding of incisors and canines,malocclusion, malalignment, absence of 2nd premolar, spacing of teeth were observed in high arched palategroup
