AIM:To evaluate the effect of femtosecond laser assisted cataract surgery combined with triple-focus intraocular lens implantation in the treatment of cataract. METHODS: Totally 86 cases(106 eyes)of patients with double cataract in our hospital from January 2016 to January 2017 were selected, including 49 cases(59 eyes)were set as the observation group(treated with femtosecond laser assisted phacoemulsification combined with triple-focus intraocular lens implantation), and 37 cases(47 eyes)were set as the control group(received traditional phacoemulsification combined with triple-focus intraocular lens implantation). Corneal endothelial cell density, cumulative dissipated energy(CDE), distant and near visual accommodation before and after operation were compared between the two groups, postoperative complications were observed. RESULTS: The preoperative corneal endothelial cell density of two groups had no significant difference(P>0.05). The corneal endothelial cell density of two groups significantly decreased at postoperative 1wk, with statistic significance within groups(PPPPPP>0.05). The incidence of glare and halo in the observation group was 10.2% and 8.5% in the control group, and are in the patients whose age was above 60 years old, there was no significant difference between the two groups(P>0.05). CONCLUSION: Femtosecond laser assisted cataract surgery combined with triple-focus intraocular lens implantation in the treatment of cataract can not only improve curative effect, but also provide high safety, while the adverse events including glare, halo and other adverse visual circumstances should be considered after triple-focus intraocular lens implantation.

Seven new species of the Scaptodrosophila brunnea species group are described from east Asia: S. maculata sp. n., S. melanogaster sp. n., S. nigricostata sp. n., S. nigripecta sp. n., S. obscurata sp. n., S. protenipenis sp. n. and S. rhina sp. n. Three known species, S. parabrunnea (Tsacas & Chassagnard), S. pressobrunnea (Tsacas & Chassagnard) and S. scutellimargo (Duda) are redescribed. A key to all the examined species in the brunnea group is provided. Species delimitations have been improved by integrating the DNA sequences with morphological information. The intra- and interspecific pairwise p-distances (proportional distance) are summarized. Some nucleotide sites with fixed status in the alignment of the COI sequences (664 nucleotide sites in length) are used as “pure” molecular diagnostic characters to delineate species in the brunnea group.

AIM: To investigate the effect of femtosecond laser assisted cataract surgery and conventional phacoemulsification surgery on corneal endothelial cell morphology and function. METHODS: This study included 80 cases of cataract patients(88 sicked eyes)treated in our hospital from January 2016 to January 2017. All patients underwent phacoemulsification combining with intraocular lens implantation for treatment. Based on the review of treatment, 40 cases(43 sicked eyes)receiving femtosecond laser assisted cataract surgery were included into the observation group, 40 cases(45 sicked eyes)receiving conventional phacoemulsification only were divided into the control group. The proportion of patients whose postoperative uncorrected visual acuity >0.5 of the two groups were compared, and sac diameter, capsule size, intraoperative cumulative energy release(CDE)were recorded, the corneal endothelial cell density and variation were recorded before and after operation, the preoperative and postoperative ratio of hexagonal cells were compared between the two groups subsequently. RESULTS: At 1d postoperatively, uncorrected visual acuity >0.5 of the observation group was no significant difference with that of the control group; the ratio was 74% at 6mo after surgery, which was significantly higher than that of the control group(53%), there was statistical significance(PPPCONCLUSION: Femtosecond laser assisted cataract surgery can reduce the effect of ultrasound energy on cornea, and can sharply decrease the damage to corneal endothelial cell morphology and function.
