【摘要】目的觀察三焦點人工晶狀體（IOL）植入術(shù)后長期療效。方法選取行三焦點IOL植入術(shù)的患者30例（50只眼），于術(shù)后6個月及12個月分別測試及隨訪。比較術(shù)后6、12個月視力情況、離焦曲線、后發(fā)性白內(nèi)障、問卷調(diào)查結(jié)果。結(jié)果術(shù)后6個月遠視力（0.038±0.06），中間視力（O.112±0.063），近視力（0.078±0.058）;術(shù)后12個月遠視力（0.040±0.049），中間視力（0.108±0.06），近視力（0.060±0.053）。術(shù)后12個月與6個月遠、中、近視力比較差異均無統(tǒng)計學(xué)意義（F=0.03、0.106、2.596，P>0.05）。術(shù)后6、12個月患者離焦曲線均在0.0 D處為最高峰，在+1.0 D-2.5 D離焦范圍內(nèi)平緩且處于較高值，視力均>0.2LogMAR。所有患者中僅一眼術(shù)后8個月時發(fā)生較明顯后囊膜混濁，并行YAG激光切開治療，激光后視力恢復(fù)至術(shù)后3個月水平。所有患者中有2只眼出現(xiàn)光暈，但不影響其日常生活，未見其他不適。

結(jié)論三焦點IOL植入可長期為患者提供良好的全程視力，且患者主觀滿意度較高，視覺質(zhì)量較好。

【Abstract】Objective To observe the long-term efficacy of trifocal intraocular lens （IOL） implantation.Methods

A total of 30 patients （50 involved eyes） with trifocal IOL implantation in our hospital were testedand followed-up for 6 and 12 months after surgery. The visual acuity. defocusing curve， post-cataract andquestionnaire survey results 6 and 12 months after surgery were compared. Results 6 months after surgery， thefar vision. intermediate vision and near vision were （0.038±0.06）. （0.112±0.063） and （0.078±0.058）. which were.（0.040±0.049）. （0.108±0.06） and（0.060±0.053）12 months after surgery. There was no statistically significantdifference in far. intermediate and near vision between 12 months and 6 months after surgery （F=0.03，0.106， 2.596.P>0.05）. 6 and 12 months after surgery， the defocusing curve of the patients was the highest at 0.0 D， and thedefocusing curve was gentle and high in the range of +l.O D to-2.5 D. and the visual acuity was > 0.2 LogMAR. Inall patients， only I eye had significant posterior capsule opacification 8 months postoperatively. After YAC laserincision. the visual acuity recovered to 3 months postoperatively. Halo appeared in 2 eyes of all patients， but it didnot affect their daily life， and no other discomfort was found. Conclusion Trifocal IOL implantation implantationcan provide good whole course vision for a long time， and patients have higher subjective satisfaction and bettervisual quality.

目前白內(nèi)障手術(shù)不僅僅是復(fù)明手術(shù)，而是一種屈光性手術(shù)。手術(shù)后獲得清晰、舒適、持久的全程視力及良好的視覺質(zhì)量是醫(yī)患共同目標(biāo)。近年來隨著人們生活質(zhì)量提高，中距離視力越來越受到關(guān)注，以往的IOL在中距離視力方面顯得不夠。ATLISA tri 839MP三焦點IOLf德國Carl ZEISS公司）的光學(xué)區(qū)在近距離增加+3.33 D，中距離補充+1.66 D，可以明顯改善中間視力[1-3]，為醫(yī)患雙方提供更多的選擇。本研究擬探討術(shù)后長期療效。
