AIM: To observe the postoperative visual quality and patient satisfaction of AT LISA Toric 909MP(909M)astigmatic corrected multifocal IOL and AT TORBI 709M(709M)astigmatic corrected single-focus IOL after phacoemulsification.

METHODS: Patients with age-related cataract and corneal astigmatism(>1.0D)were enrolled and accepted phacoemulsification combined with implantation of intraocular lens(IOL)in our hospital during December 2017 and December 2018. Forty cases(56 eyes)were divided into two groups according to which IOL they chose, multiple focal astigmatism(909M)group included 23 cases(35 eyes), single focal astigmatism(709M)group included 17 cases(21 eyes). Three months postoperatively, the visual acuity, defocus curve, residual astigmatism degree, rotational stability of the IOL, postoperative visual quality analysis and patient satisfaction were evaluated.

RESULTS: At 3mo postoperatively, uncorrected distance visual acuity(UDVA)and corrected distance acuity in the two groups were significantly improved(P<0.05). The defocus curve showed that 909M group had two visual acuity peaks at 0D and -2.5D, and a low peak at -1D, 709M group had the visual peak only at 0D. Spectacle independency was achieved by 91%(21/23)of patients in the 909M group and 18%(3/17)in the 709M group.

CONCLUSION: Both of the 909M and 709M had good correction effect for cataract combined with astigmatism. It provided better rotational stability. In addition, 909M provided excellent distance, near visual outcomes, and acceptable intermediate vision. At the same time, it improved the spectacle independency and satisfaction of cataract patients combined with astigmatism.

OBJECTIVETo elucidate the long-term effect of repeated febrile convulsions (FC) on seizure susceptibility in immature rats.

METHODSWarm-water-immersion rat FC model was developed with SD rats 22 days of age, 15 attacks of seizures were induced in the rats every other day, and some of the rats were left un-stimulated for 3 months, then were re-stimulated. Seizure phenomenon was observed, including the latency and the duration of seizures and the temperature of rats. Hippocampal neuron loss and mossy fiber sprouting were detected by thionine staining and Timm staining.

RESULTSAfter the 15th bath, the latency, the duration of seizures, and the temperature of rats were respectively (4.3 +/- 0.8) min, (5.5 +/- 2.9) min, (42.2 +/- 0.7) degrees C. Three months later, on re-stimulation, in 14 of 19 rats with previous FC experience seizures occurred while in only one of 13 non-FC rats seizure occurred and lasted for 8.5 min. Three months later, the latency, the duration of seizures, and the temperature of rats were respectively (5.4 +/- 0.6) min, (19.3 +/- 5.1) min, and (42.4 +/- 0.4) degrees C (4 rats with status epileptics were not included). The incidence of seizures on re-stimulation in rats of FC group (74%) was significantly higher than that in non-FC group (8%) (chi(2) = 13.50, P < 0.01), and the duration of seizures [(19.3 +/- 5.1) min] was significantly longer than those induced in early life [(5.5 +/- 2.9) min] (t = 10.49, P < 0.01). After the 15th bath, no significant change was demonstrated in rats of different groups. While 3 months later, prominent neuron loss was observed in hippocampal CA(3) region in rats with previous FC experience (P < 0.01). Significant mossy fiber sprouting phenomenon was detected after the 15th bath and 3 months later (P < 0.05).

CONCLUSIONRepeated FC in early life enhances long term susceptibility of rats to seizure.
