One of the most recent advancements in the field of cataract surgery is optical biometry. With the advent of optical biometry ocular measurements are now simpler, quicker, and more precise. The devices have made intraocular lens (IOL) power calculations easier in difficult situations too, such as in cases with extremes of axial lengths, silicone filled eyes, cataract surgery in post-keratoplasty eyes, post Laser-Assisted in Situ Keratomileusis (LASIK) eyes, etc. The gold standard for IOL power calculation in the present day is by the use of optical biometry devices. The anatomical measurements by these devices are highly precise and because of these measurements and the incorporation of various IOL power calculation formulas the optical biometry devices give the accurate power and the post-operative visual outcome is highly satisfactory among the patients. The growing use of these devices has made cataract the most commonly performed refractive surgical procedure nowadays. In the current scenario, optical biometry has widespread acceptance in almost all countries and has many advantages over ultrasound or immersion biometry. Cataract surgeons can obtain easy and reliable measurements from these devices. Refractive surprises have also decreased considerably with their use. This article will comprehensively review the principles of the various optical biometry devices, the parameters used in each of the devices, the advantages and disadvantages, and add more like what all this article will add.
白内障手术领域的最新进展之一是光学生物测量法。随着光学生物测量法的出现，眼部测量现在变得更简单、更快捷且更精确。这些设备在困难情况下也使人工晶状体（IOL）的屈光度计算变得更容易，比如在眼轴长度极长或极短的情况、硅油填充眼、角膜移植术后眼睛的白内障手术、准分子激光原位角膜磨镶术（LASIK）术后眼睛等情况。当今人工晶状体屈光度计算的金标准是使用光学生物测量设备。这些设备进行的解剖学测量非常精确，并且由于这些测量以及各种人工晶状体屈光度计算公式的纳入，光学生物测量设备能够给出准确的屈光度，患者术后的视觉效果也非常令人满意。这些设备的广泛使用使白内障手术成为如今最常进行的屈光手术。在当前情况下，光学生物测量法在几乎所有国家都得到广泛认可，并且与超声或浸入式生物测量法相比有许多优势。白内障手术医生可以从这些设备中轻松获得可靠的测量结果。使用这些设备后，屈光意外情况也大幅减少。本文将全面回顾各种光学生物测量设备的原理、每个设备所使用的参数、优缺点，以及本文还将补充的更多内容。
