• Dear sir, Two years before I have checked eyes of my son who is 13 years of age now, the power came to @ - 1.5 on both the eyes.After that he has checke the eyes recently the power came to -3.0 to left & -2.25 to right eye. I fear what will happen if the power will go on increasing with this speed. Kindly suggest me the remedies to come down the power & not further increasing the same. 

It is normal for a child's spectacle power to increase in this age. It is solely decided by hereditory factors, and reading, computer, TV etc have not role to play. Generally the power increases till age of 18 to 20 yrs. It is best to wear glasses presently, but after 14 he can switch over to contact lenses and after 18 to 20, to Lasik. Get his eyes check up annually. He needs retinal check up once in 3 years. Thanks, Sincerely, M.S.Ravindra

• Greetings to Dr. Karthik 
  I am back in Dubai, thanks for the treating my eye problem, I am feeling there is improvement of about 70%, still experiencing floatation of particles.
  Should I continue  the eye drops Nepalact in both eye & Predac in the left eye 
  
  
  Pl advice             
  

• I have cylindrical power of -3.5 on both the eyes, i am a man aged 23. i use spectacles while using system and occasional for other type of works. i work in software industry so my full work depends only with computer. I used spectacles for the past 3 years, but use occasionally so got increased from -2.5 to -3.5 right now.
  So now i prefer to go with contact lenses, toric ah ?? can i prefer contact lens rather than spectacles. Suggest me the best. Thanks in advance      
  

Sir, you have 3 options, all are equally good. Spectacles, toric or RGP contact lenses and Lasik. Kindly get a Topography or Pentacam to see to which you are suited, and than decide. These tests also rule out if you have Forme fruste Keratoconus. Thanks.

• I have one query. My eye power is -7. I have come across a few people with similar power range who underwent lasik. All of them took 3-4 weeks to regain normal vision after the surgery and had difficulty working with computers during this time. Is this expected with such high powers such as mine? Does the recovery period depends upon the machine/technique used? Also, the people with lower eye power i.e. below 5 recovered in few days time.
  
  Will VisuMax help reduce recovery period or does it depends on person to person? Or the 'Allegretto 400 Eye Q' that you have at your centre as good as VisuMax?

• At this time Allegretto is the best machine. Indeed, VisuMax has delayed recovery of vision, even in its latest version, which is installed in Baroda. The recovery is immediate. Next day you will have good vision. Near vision may be strenuous (not blurry!) for all myopes, if they have used undercorrected glasses or no glasses in the past. For those who have used full power correction, this is not so. There is no reason why the delay has taken 3 to 4 wks, and the results are certainly machine as well as surgeon dependent. Thanks

• Respected Sir,
  I have one female patient details as follows :
  Age 21 yrs
  Working woman
  Refractory Power -1.00 Dsph
  Topography K1 44.82 87
                         K2 45.02
  Pachymetry : 475
  
  She wishes to go for refractory Procedure.
  Which procedure do you advise ? PRK or Lasik with 110 Head
  If Prk: what will be the PTK Depth & mechanical or with the help of laser
  Mitomycin is advisable? for how long?
  
  My parameters
  PRK with laser PTK for depth of 50micron for 8 mm zone and then laser which will ablate nearly 13 to 14 micron for 6 mm zone and than mitomycin 0.002 % for 20 min and through Wash with chilled BSS and than Bandage CL for 3 to4 days. I will go for Moxigram drops 4times along with Refresh Liquigel 4times with oral inflammatory drug and Vit A for 5 days. After removal of CL i will start Prednisolone drops 4 times for 2 months.
  
  Please guide me and give your expert opinion.
  
  Next for Hyperopic patients PRK is more help than Lasik? Reason? What is your choice for low myopia?

• In my experience, transepithelial PTK never gives a good starting point for the refractive part of the procedure. I have done many, but not happy with the refractive results. PTK ablates differently in the centre and periphery. Best is to go for alcohol removal of epithelium, which gives a nice Bowmans layer to begin PRK.
  
  Check the nomograms on your machine. For low myopia like this, we generally do over correction by half D or so. It is machine dependent. Post PRK, you dont need to use pred at all. I use tid Flurbiprofen, tid FML and tears all for one month. Contact lenses are out on 4 th day. Mitomycin not needed if ablation depth is below 45 to 50 u. If more, titrate from 30 to 120 secs depending upon the depth of ablation. Better to err on higher side. Hyperopia, I prefer thin flap Lasik, as central thickness is not a concern.
