Purpose: To evaluate the postoperative outcome of Tecnis? ZCB00 1-Piece acrylic intraocular lens (IOL), the new single piece, aspheric IOL until 12 months. Methods: Sixty eyes undergone cataract surgery using two different IOLs; The Tecnis? ZCB00 1-Piece Acrylic IOL (30 eyes) and the Tecnis? ZA9003 3-Piece Acrylic IOL (30 eyes). Cataract surgery was performed in the same period. All complicated cases were excluded. Best corrected visual acuity (BCVA), refractive error, photopic and mesopic contrast sensitivity, total high order aberration, spherical aberration and anterior chamber depth were measured preoperatively and at 1, 6 and 12 months after surgery. Results: There were no statistically significant differences between two groups in BCVA, refractive error, total high order aberration and spherical aberration all the time after surgery. Both groups have negative ocular spherical aberration until 12 months after surgery. 1-piece and 3-piece groups had different tendency in axial movement. But there were no statistically significant differences in anterior chamber depth measured at 1 week, 1, 6 and 12 months after surgery. There was no statistically significant difference in contrast sensitivity at 1, 6 and 12 months after surgery. Conclusions: The Tecnis? ZCB00 1-Piece acrylic intraocular lens (IOL) showed comparable clinical outcomes to the Tecnis? ZA9003 3-Piece acrylic intraocular lens (IOL) until 12 months after cataract surgery. 1-piece and 3-piece IOL group had different tendency in axial movement. However, refraction remained stable during 12 months after surgery. Mostly, both IOL groups had negative ocular spherical aberration during whole follow-up period.

목적: 일체형 비구면 인공수정체 Tecnis(R) ZCB00를 삼체형 비구면 인공수정체 Tecnis(R) ZA9003와 비교를 통해 장기 임상 결과를 알아보고자 하였다. 대상과 방법: 일체형 비구면 인공수정체 및 삼체형 비구면 인공수정체를 삽입한 각각 30안을 대상으로 술 후 12개월째까지 최대교정시력, 굴절이상, 대비감도, 전체 고위수차 및 구면수차, 전방깊이를 측정하여 분석하였다. 결과: 모든 시기에서 측정한 최대교정시력, 굴절이상, 전체 고위수차, 구면수차는 통계적으로 유의한 차이가 없었으나, 구면수차는 양군 에서 대부분의 추적 관찰 기간 동안 음의 값을 나타냈다. 수술 후 1주, 1개월, 6개월, 12개월째 측정한 전방 깊이 검사에서 서로 다른 방향성을 보였으나, 통계학적으로 유의한 변화는 없었으며 굴절값은 안정적으로 유지되었다. 대비감도 검사에서 양 군간 유의한 차이는 없었다. 결론: 일체형 비구면 인공 수정체 Tecnis(R) ZCB00의 술후 12개월까지 임상 결과는 기존 안정성이 입증된 삼체형 비구면 인공수정체와 대등한 결과를 보였으며, 유의한 전방깊이의 변화는 없었다. 술후 안구 구면수차는 대부분의 경과관찰 시점에서 양군에서 모두 음의 값을 나타냈다.

There are increased interests in using new regeneration energy due to the effect of the latest rising oil price. On this account, various practical applications using small stand-alone PV generation system are being made. In this paper, with intent to change mercury lamp using for existing garden lamp with high flux LED, we have considered load characteristic using high flux LED modules applied to PV system It is simulated with PSIM and made experiment set with a 75[W] solar cell module, DC-DC converter, controller and battery.
