When implanting a posterior chamber phakic intraocular lens (pIOL), it is crucial to maintain a safe distance. The patient was a 29-year-old man with high-degree bilateral myopia. In February 2021, posterior chamber acrylic pIOLs (Eyecryl Phakic TORIC; Biotech Vision Care, Gujarat, India) were implanted in both his eyes. After the surgery, the right eye vault was 6 μm, and the left eye vault was 350 μm. Moreover, the internal anterior chamber depth values were 2,270 and 2,220 μm for the right and left eyes, respectively. In our case, we found a fairly high crystalline lens rise (CLR) in both eyes, but it was greater in the right eye. The CLR value was +455 in the right eye and +350 in the left eye. In our patient, anterior segment anatomical parameters were higher in the right eye than in the left eye, and a greater pIOL length was calculated for the right eye, but the vault was very low. In our opinion, this was associated with the high CLR in the right eye. If an even larger pIOL had been implanted, there would have been a greater narrowing of the anterior chamber angle. This case would be contraindicated if those parameters were considered in selecting the indications and determination of the pIOL length.
植入后房型有晶状体眼人工晶状体（pIOL）时，保持安全距离至关重要。该患者为一名29岁的双侧高度近视男性。2021年2月，其双眼均植入了后房型丙烯酸酯pIOL（Eyecryl Phakic TORIC；印度古吉拉特邦Biotech Vision Care公司）。术后，右眼房高为6μm，左眼房高为350μm。此外，右眼和左眼的前房内深度值分别为2270μm和2220μm。在我们的病例中，我们发现双眼的晶状体抬高（CLR）相当高，但右眼的更高。右眼的CLR值为+455，左眼的为+350。在我们的患者中，右眼的眼前节解剖参数高于左眼，且计算出右眼的pIOL长度更长，但房高非常低。我们认为，这与右眼较高的CLR有关。如果植入更大的pIOL，前房角会进一步变窄。如果在选择适应证和确定pIOL长度时考虑这些参数，该病例将为禁忌证。
