亮点
单眼视理论可能导致立体视觉的丢失,就像这位患者单眼植入单焦后的状况;
取出单焦以三焦点取代,重新植入囊袋三天后患者的未矫正视力可达20/20;
高患者满意度:术后完全不依赖眼镜且仅有最小程度上的眩光及光晕。
简介
单眼视觉是一种常见的以人工晶体治疗老花眼的方法,这一技术也同样常被用于白内障与屈光晶体置换的治疗当中。一般而言,选择正常眼作为主视眼用来修正远景,选择近视眼(-1.5 to -2.0D)作非主视眼修正近景。患者的大脑一般需要花上4-6周时间来适应用远焦眼观察远景、近焦眼观察近景的这一过程。
本文所述这一案例报道了一名接受单眼人工晶体植入的患者在术后三个月后向主治医生寻求其他解决方案的情况,该患者对于单眼植入单焦的术后效果感到非常不理想。
结果
置换手术完成三天后,患者为其视力在未矫正过的双眼视觉下能达到20/20而感到非常开心,同时每只眼未矫正的视力可达0.8 dec.。一个月后,患者主视眼(视远)视力可达20/20,双眼视力能达1.25 dec.,近距离下视力则有20/25。患者对该结果相当满意,全距离视力下都不必再依赖于眼镜,同时眩光和光晕的现象也仅有最小程度。
Successful treatment of an unhappy monovision patient with the trifocal AT LISA tri

Highlights
A monovision approach can lead to loss of binocularity,like with this patient implanted with monofocal IOLs with one eye; 
 After conversion of monofocal pseudophakia into multifocal pseudophakia using the AT LISA tri 839MP the patient reached 20/20 in uncorrected binocular conditions after three days; 
 High patient satisfaction: Extreme patient satisfaction was achieved along with complete spectacle independence and minimum halos and glare.
Introduction
Monovision is a very popular method to compensate pseudophakic presbyopia. This technique is used both in cataract surgery and refractive lens exchange. Usually, emmetropia is targeted in the patient’s dominant eye to correct distance vision, and myopia (-1.5 to -2.0 D) is targeted in the non-dominant eye to correct near vision. The patient’s brain normally learns within 4-6 weeks to use the distance focused eye for distance viewing and the near focused eye for near viewing.
The case reported here is a patient who underwent a pseudophakic monovision procedure and after 3 months of follow up, came to us for a second opinion. The patient was dissatisfied with the outcome.
Results
Three days after the second procedure, the patient was very happy as he could reach 20/20, in uncorrected binocular conditions, while each eye individually was 0.8 dec. uncorrected, binocular near vision was J3. One month later, the patient was 20/20 for far monocular and binocular 1.25 dec.. Near vision was 20/25 (0.8 in the LogRad charts). Extreme patient satisfaction was achieved. The patient was spectacle independent for all distances.
Minimum halos and no glare were reported by the patient, who was overall very happy with the outcome.
