Brief Summary:
There have been numerous studies comparing various ACD measurements in phakic eyeswhile researches comparing ACD in pseudophakic eyes are less extensive With the recent popularity of presbyopia correction measuring the ACD will facilitate differentiating pseudophakic accommodation from pseudoaccommodation It is thus mandatory to verify the accuracy of ACD measurement of these devices since the innovation of various IOLs in the recent decade makes this task more complicated In this study we will assess the limitations of using Pentacam for ACD measurement in pseudophakic eyes and compare Pentacam measurement with IOLMaster and A-scan measurements
Detailed Description:
In this prospective study ACD was measured in 90 phakic and 94 pseudophakic eyes by Pentacam IOLMaster and A-scan Correlations and differences between the three measurements were investigated The accuracy in detecting the anterior lens surface in pseudophakic eyes was also assessedDifferences in ACD-Pen ACD-IOLM and ACD-A were analyzed using one-way analysis of variance ANOVA When an overall significance of P 005 was obtained pair-wise comparisons were made using Tukeys multiple comparison t tests The association between ACD-Pen ACD-IOLM and ACD-A was assessed using Pearsons correlation test The distribution of erroneous ACD-Pen measurement for the three IOLs was analyzed with the chi-square test In all analyses P 005 was considered statistically significant
