“…Pentacam HR (-9.42%). Our results corroborate the findings obtained by Kanellopoulos et al, 32 showing a reduction of the µ-chord from 0.12 to 0.05 mm (50%) and a photopic and mesopic pupil diameter reduction of -9.8% and -9.1%, respectively, after cataract surgery.…”

“…The correlation between pupil change of Pentacam and difference in µ-chord after surgery suggest that the variation in µ-chord is mainly due to the variation of pupil center position with pupil diameter change as it has been previously reported. 32 The µ-chord, which is correlated with kappa angle, 26,33 has been hypothesized to be related with the visual performance achieved with MIOLs. 34 However, to this date, there is only one clinical study that correlates the kappa angle with the visual performance.…”

“…That is, pupil size was not taken into account in this study. Cataract extraction surgery is known to affect pupil size and centration [ 28 , 29 ]. However, none of our patients had any pupillary abnormalities and their pupils were within the normal size range after the cataract surgery.…”

Effect of diabetic retinopathy and diabetes on the intraocular straylight in pseudophakic eyes

BackgroundThe aim of this study was to prove the relationship between the intraocular straylight level and diabetic retinopathy (DR) according to disease severity. Also, we aimed to evaluate whether diabetes mellitus (DM) per se could be a risk factor of increased intraocular straylight although we did not rely on a definite sign of DR in this study.MethodsIn this prospective comparative study, ninety three eyes were enrolled and divided into four groups as follows: Group 1 (26 eyes), without DR or DM; Group 2 (25 eyes), with DM but without DR; Group 3 (21 eyes), mild to moderate non-proliferative DR; and Group 4 (21 eyes), severe non-proliferative DR. To measure the intraocular straylight in an objective manner, the C-quant straylight meter was used to preoperatively and 2 months postoperatively in all patients who underwent phacoemulsification surgery. All the patients also underwent a macular optical coherence tomography and hemoglobin A1c (HbA1c) analysis. A comparison of straylight levels adjusted by age among four groups was performed postoperatively.ResultsThe postoperative level of intraocular straylight was statistically significantly different among four groups (P <0.05). When adjusted for ages, Group 4 showed the highest straylight level when compared with Group 3 and the other two groups (P <0.05). Group 1 showed the lowest straylight level in comparison with Group 2 and the other two groups (P <0.05). There was no significant correlation between HbA1c level, duration of diabetes and postoperative straylight level.ConclusionsThe level of intraocular straylight at 2 months postoperatively had a tendency to increase as the severity of DR increased. Additionally, the straylight level was higher in DM patients without DR than in patients without DM. Therefore, the severity of DR seemed to influence the intraocular straylight level. Although there is no definite sign of DR, DM per se can be a risk factor for increasing intraocular straylight. In conclusion, the level of intraocular straylight seems to be a sensitive test for detecting early retinal damage secondary to DM.

“…Multifocal IOLs with concentric refractive ring design may benefit from a central zone that is smaller than the photopic pupil diameter (32). In many cases, the postoperative pupil is significantly smaller than the preoperative pupil (33,34). The preoperative pupil size has limited ability to assist the choice of well-suited refractive multifocal or aspheric IOLs.…”
