Abstract

Purpose
To investigate the clinical results of femtosecond laser-assisted cataract surgery (FLACS) in eyes previously implanted with a posterior chamber phakic intraocular lens (PIOLs).
Methods
The medical records of 27 eyes were retrospectively reviewed. Each eye had history of implantation of posterior chamber PIOLs and newly got FLACS. Complications of intraoperative anterior capsulotomy and lens fragmentation were investigated. Uncorrected and corrected visual acuities (UCVA and BCVA), keratometric and manifest refraction (MR) values were compared preoperatively and postoperatively 1 day, 2 months and 6 months.
Results
All eyes completed anterior capsulotomy without any intraoperative complication. However, 13 eyes out of 18 eyes experienced incomplete lens fragmentation. Vaultings of 5 eyes with complete lens fragmentation were 460.40 ± 199.11 μm (0.84 ± 0.35 corneal thickness [CT]) and vaultings of the other 13 eyes with incomplete lens fragmentation were 225.85 ± 151.2 μm (0.43 ± 0.29 CT). 2 eyes with vaultings of 460 μm and 412 μm failed to complete lens fragmentation due to corneal opacity. All eyes could be completed whole surgery without additional complications.
Conclusions
FLACS in eyes with posterior chamber PIOLs is useful to execute anterior capsulotomy. However, there is a limitation in doing lens fragmentation because of bubble accumulated under PIOLs.
