“…The more recent optical techniques include partial coherence interferometry (PCI), optical low coherence reflectometry (OLCR), optical low coherence interferometry (OLCI), and most recently, swept source-optical coherence tomography (SS-OCT) [ 3 ]. The increased life expectancy of the worldwide population has been accompanied by an increase in the pursuit of perfect postoperative refractive visual quality expectations [ 4 ], especially for cataract patients, who have a higher desire for glasses independence after surgery. In other words, in addition to routine measurement, the evaluation of corneal parameters with wavefront analysis, including PK, TK and TNP, plays an important role in the preoperative assessment in cataract surgery, especially in eyes that have had prior refractive corneal surgery and in patients who desire a premium IOL [ 5 ].…”

Purpose To assess the differences and similarities in the corneal curvature obtained by two swept-source optical coherence tomography (SS-OCT) devices, Scheimpflug imaging system and one ray tracing aberrometer in patients with cataracts. Moreover, this study aimed to compare the differences in posterior corneal (PK), total corneal (TK) and true net power (TNP) measurements among the IOLMaster 700, CASIA2, and Pentacam. Methods A total of 200 eyes of 200 patients (116 female, 58%) were enrolled in this study, with a mean age of 65.9 ± 9.5 years. The flattest (Kf), steepest (Ks), and mean cornal powers (Km), J0, and J45 were obtained using two SS-OCT-based biometric devices, one rotating camera system and one ray-tracing aberrometer. The PK, TK and TNP values were also measured using these devices. To evaluate the differences and similarities between the devicves, the Friedman test, Pearson correlation coefficient (r), intraclass coefficient correlation (ICC) and Bland‒Altman plots with 95% limits of agreement (LoA) were used, and boxplots and stacked histograms were generated to describe the distributions of the data. Results There were no significant differences between the IOLMaster 700 and Pentacam for any of the keratometry values. Additionally, there were no significant differences between the IOLMaster 700 and iTrace in evaluating J0 and J45. Bland‒Altman plots revealed relatively wide LoA widths, almost larger than 1 diopter for the keratometry values and almost larger than 0.5 diopter for J0 and J45 values among the four devices. In terms of PK and TK values, significant differences and low ICCs were found among the three devices. Conclusions Although strong correlations and good agreement were found among the IOLMaster700, CASIA2, Pentacam and iTrace for Kf, Ks, Km and J0, J45, it seems that the measurements should not be used interchangeably because of the wide LoA widths and the presence of significant differences among the devices. Similarly, due to significant differences and low ICCs, the PK, TK and TNP values obtained by IOLMaster 700, CASIA2, and Pentacam should not be used interchangeably.

“…Nevertheless, recent advances in IOLs design and biometry have further increased patients and doctors' expectations form cataract surgery. It is considered not only as an operation that restores vision but as a refractive procedure that minimizes if not eliminates the use of glasses [3][4][5].…”

Purpose To identify the rate and characteristics of cataract surgery candidates suitable for multifocal intraocular lens (MIOL) implantation among patients undergoing preoperative evaluation in a public hospital. Materials and Methods Screening was performed based on patient’s medical record, comprehensive ophthalmic examination, optical biometry (Zeiss, IOL Master 700) and Optical Coherence Tomography (Heidelberg, OCT Spectralis) in accordance with the relative indications and contraindications as mentioned in pertinent literature. Results The study evaluated 1200 consecutive patients. Four hundred and thirty -two patients (36%) were not eligible for bilateral surgery and were excluded from the study. Of 768 patients included in the present study 346 (45.1%) were considered suitable candidates. Four hundred twenty-two patients (54.9%) had reasons of exclusion in one or both eyes. Among them 121 (28.7%) were excluded because of retinal disease, 120 (28.4%) due to regular astigmatism (> 1.0 D of corneal astigmatism), 32 (7.5%) due to pseudoexfoliation or zonular instability, 30 (7.1%) because of glaucoma or ocular hypertension while in 90 (21.3%) patients there were multiple reasons of exclusion. Suitable candidates were significantly younger (70 and 75 years respectively (p < 0.001). After being informed about potential risks and benefits of MOIL implantation 212 of 346 (83.8%) eligible patients would consent for it. Conclusion Close to half of cataract patients in a public hospital are eligible for MOIL implantation and the majority would procced with the operation. The most prevalent contraindication is macular disease.
