白內障是因為水晶體變得混濁，使影像模糊不清，讓生活大受影響。透過手術移除混濁的水晶體，並放入人工水晶體，才能改善視力。〔1〕
散光是成年人身上最常見的屈光異常之一，若能確實矯正散光，有助於提升患者在接受白內障手術後的視力表現，並降低眼鏡配戴率。〔1〕
傳統單焦點散光人工水晶體能看清楚遠處物體，至於中、近距離則需要配戴老花眼鏡輔助。〔2〕
國際大廠短焦延伸焦距散光矯正人工水晶體的散光矯正技術，大幅提升術後穩定度〔5〕，使視力更加清晰，提供遠距離清晰視力外，更延伸單焦點視覺景深，改善中距離視力。〔2〕
適合用於切菜煮飯、開車看導航、使用電腦、平板、打牌下棋等活動，滿足多數人用眼需求，提升日常生活便利性。〔2〕
具有散光矯正功能的短焦延伸焦距人工水晶體，可同時解決白內障與散光，並在暗光下提供高對比夜間視力，減少意外發生。〔3〕,〔6〕
低折射、低色散的晶體材質，可減少色像差，視力更清晰，不僅日間方便、夜間也安全。〔3〕
人工水晶體的種類非常多，術前要與醫師充分溝通，根據用眼需求，選擇合適的人工水晶體。〔7〕
術後兩個星期內不可趴睡、一個月內眼睛不可以碰到水，遵從醫師的指示小心照護，重拾睛彩人生！〔8〕
