RK incisions with Lasso suture to minimize hyperopia | Post Clear Lens Extraction with Toric IOL
Case Study: Post Radial Keratotomy Patient receives Toric IOL Implants ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1988 RK OU (Western Mass)
2002 Lasso Suture OS for progressive hyperopia (University Center)
2007 Presents to Boston Eye Group, wants less dependency on glasses.
MR OD = +2.50 -2.00 090 20/20
MR OS = +3.25 - 2.75 130 20/20
2008 Lasso suture removal OS to assess underlying Rx:
Post op RX OS = +7.25 -4.25 x 118
12/2008 Clear Lens extraction (CLE) with Toric IOL OS:
Post CLE UCVA : 20/25
3/2009 CLE/Toric IOL OD
Post CLE UCVA 20/30
This case was made difficult by the prior RK, progressive hyperopia and difficulty with IOL calculations after refractive surgery. He ended up with excellent results as biometry formulae are now more refined and the Toric IOL is an impressive addition to the IOL options available to us.

| Wavefront-guided LASIK delivers significantly better night driving performance than conventional LASIK
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This comparative study prospectively assessed simulated night driving performance both before and six months after wavefront-guided (wLASIK) with a femtosecond laser flap and conventional LASIK (cLASIK) using a mechanical keratome for the treatment of moderate myopia. After surgery, performance on the night driving simulator testing decreased 32 to 38 percent (data was collected from two prospective clinical trials) in cLASIK eyes for all tasks, compared to 0 to 3 percent reduction with wLASIK. Performance improved significantly in 11 to 31 percent of the wLASIK group in every task compared to 2 to 7 percent increase in the cLASIK group. The researchers note that wLASIK also improved mean visual performance compared with spectacles. (Ophthalmology, April 2009)
