Table 4.

Pre- and postoperative average peripapillary retinal nerve fiber layer (pRNFL) thickness changes in the pseudophakic and control eyes.

	pRNFL (μm) among the pseudophakic group	pRNFL (μm) among the control group	P value^b
Baseline	90.28 ± 22.31	91.20 ± 21.58	0.848
At 3 months (P value^a)	88.78 ± 22.55 (0.335)	89.69 ± 21.76 (0.276)	0.850
At 6 months (P value^a)	88.67 ± 23.14 (0.387)	88.73 ± 21.08 (0.082)	0.990
At 12 months (P value^a)	87.62 ± 23.04 (0.158)	87.33 ± 20.67 (0.007)	0.951
At 18 months (P value^a)	87.32 ± 22.61 (0.110)	87.23 ± 20.54 (0.006)	0.984

^a P value, compared with values at baseline (paired t-test). ^bP value, comparison of average pRNFL changes in the pseudophakic group versus control group, at baseline and follow-up visits (independent t-test).
